Thank you! Tested it out and works just fine.
Btw, Is UOC a combined version of Undervolted and Overclocked? Same goes for EUOC?

yes, combined
EUOC also have GPU overclock speed 750MHz
no, with regular builds wifi shouldn't work
Can I install OTA updates with this kernel? If so, will I need to re-flash the kernel from TWRP?
no, you can't with stock android one rom
clean way to restore OTA possibility - flash stock boot, system & vendor again
Thank you. I have a backup of the stock boot.img, /system & /vendor folders respectively. Is it possible for me to just replace the files replaced by the kernel by pasting it in "/" using such File explorers?
No, you can't. boot, vendor and system are on different partitions. You can use "fastboot flash..." command from a computer, or maybe, if you have twrp, you might be able to to restore those partitions from a backup (but I haven't tried it)
you can try, but you need proper backup/restore method (preserve all permissions & selinux context)
so better and cleaner way is restoring whole stock images
anyway i don't care about stock and OTA, because not using it and didn't test
I just installed "Butterfly-daisy-20190824-Pie-v5.5+". Oh my gosh, it works like magic. My phone was killing every app & when I switch between & it was reloading every time. Now it's fixed like magic. 
I'm using AOSiP ROM..

Quick question. When's the best moment to flash the kernel? I guess it's right after flashing the ROM, right? Following this guide, https://github.com/tkchn/daisyinstall/blob/master/README.md right after the custom ROM and before flashing TWRP?
you can flash kernel in any time, not matter when (oh, but only in slot with installed system of cause)
you'll have to install different kernel , that will fix the problem
Thanks for the reply, but this kernel is for daisy ,right? Why should I install a different one? Please help.
some roms have problems with different kernels , did you have problem with the stock kernel? if not - kernel related
I have another noob question. Is it possible to keep the zip files in the device (sd) and flash them whenever needed?
I'll explain. For example, if I need to be away from a reliable electricity source for longer than normal (talking about days), I can just flash the underclock zip to make the battery last longer, and flash the default version as soon as I get back to civilization. The same goes if a I need extra cpu power for whatever reason. Flash the overclock and unleash the beast. Then, get back home and flash the default again fue everyday use.
Flashing kernels doesn't make me change boot partition (a/b) not anything, right? (just like old times, when flashing was straightforward).
Does this sound right? Just asking for the possibilities.

In my opinion, an easier option is install "Kernel Auditor". With this app you can change kernel settings for battery or performance as you need.
Another option is buy a battery pack.

Your warranty is now void!
We're not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this ROM
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at us for messing up your device, we will laugh at you
Features:
Pie base: CAF & Prima Tag by LA.UM.7.6.r1-04500-89xx.0
Oreo base: CAF & Prima Tag by LA.UM.6.6.r1-11000-89xx.0
Legacy base: not updated pure sources from MiCode github
(prima tag LA.UM.7.6.r1-05500-89xx / LA.UM.6.6.r1-11300-89xx.0)

• NTFS support
• F2FS support
• SquahFS support
• CIFS/SMB support
• Added CPU Hotplug (default disabled)
• Set lz4 for better zram work
• Boeffla wakelock blocker
• Added defaults rules for Boeffla wakelock blocker
• Disable vendor verify and set no verity
• CRC32: disable by default & enable toogle (average 30% I/O performance profit)

• Also in the v4 installer included fix fpc-fp gestures for the customs rom
now gestures for both fingerprints is are:
* swipe2right - paste text
* others like in rom's setting
(if you not like this - change it in the /system/usr/keylayout/uinput-*.kl)
• Memory & battery life optimization due config settings for kernel
• Added a block to wakelock from wifi
• I/O optimization
• Hide unlocked bootloader state (for apps like bank clients etc)

- DT2W fix for fts_ts [default disabled] (thanks @33bca) * tested on customs and GSIs. for latest maybe need to enable "Handwave gesture" in "Phh Treble Settings" > "Doze features" *#TODO
- Installer include Magisk preserve#TODO
<< download Pie v5.5 || download Pie v4.4 >>
<< download Oreo v5.5 || download Oreo v4.4 >>
undervolted (U) lower voltage for decrease overheat. also incredible battery saving
overclocked (OC) CPU max frequency is 2.4GHz, GPU max frequency is 725MHz
extra-overclocked (E) GPU max frequency is 750MHz (if you will face with graphical glitches - don't use it!)
Installations:
Backup boot.img, /system/lib/modules, /system/usr/keylayout and /vendor/lib/modules folders, /vendor/bin/init.qcom.post_boot.sh file if you want to go back
Flash Zip file with any TWRP recovery, wipe Dalvik cache, reboot and enjoy ^_^
Notice: if you have Magisk with modules installed maybe you'll get bootloop.
If you have Magisk don't need reinstall it after kernel because installer will save Magisk#TODO
Right way: if you have Magisk and modules - deinstall all. Then flash stock boot.img, then custom kernel, then other stuff like TWRP and Magisk.
Enough just dirty flashing kernel and then Magisk if you need it. All yours Magisk modules will preserved.
Issues:
- DT2W not work for fts_ts touchscreen
- tell me if find
