This is basically a tl;dr thread.
I don't want to make a thread that everyone will lazy to read.​

Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. It's a fully touch driven user interface; no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Disclaimer​
Code: 
/*
* Your warranty might not be void (thanks Xiaomi). However...
*
* I am 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 RECOVERY
* before flashing it! YOU are choosing to make these modifications, and if
* you point the finger at me for messing up your device, I will laugh at you.
*/

Requirements​
  • Xiaomi Mi 9 SE (of course)
  • Unlocked bootloader
  • Some knowledge on how to deal with your device... and patience.

Flashing Instructions​
I assume you've done (very) basic steps on preparing to flash your device.
  1. Reboot device to bootloader. If device is powered off, press and hold Power + Volume Down button until tinkering Mi Bunny with "FASTBOOT" text appears.
  2. Optional: Flash stock vbmeta with the following command (attached if needed):
    Code: 
    fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
  3. Under same directory as TWRP image and ADB/Fastboot executables (if ever required), type this command:
    Code: 
    fastboot flash recovery twrp-3.x.x-y-KudProject-grus.img
    Where x and y are version of TWRP you're going to flash.
  4. IMPORTANT: After flashing, immediately press and hold Power + Volume Up for about 10 seconds to reboot to recovery.
  5. Swipe the option to allow modifications. This will prevent stock ROM from replacing recovery, however be aware that you might need to reflash stock vbmeta with disabled verity after that to be able to boot stock ROM!

Notes​
  • Don't use fastboot boot to boot the recovery; it'll proceed to boot system instead using recovery's kernel. If this happens with your current kernel's boot image security patch being older than recovery one, you're basically busted as FBE keys are upgraded the time newer combination of system + vendor + boot image security patches are detected.
    If you're out of luck in this situation, the only way to resolve is to format data (just backup your data to somewhere safe before doing so).
  • If you flash disabled vbmeta, you can't flash stock MIUI zips until the original vbmeta is restored.

Wrapped key support is added into recovery just for anticipation, although not defined by default in fstab.
I can't test it since EEA device so far is on March ASB as of V10.2.5.0 stable.

Otherwise, basic functionalities including decryption should work.

Edit: grus doesn't have anti rollback enabled at this moment, but Xiaomi may enable it in the future...

Thanks for the work! Great seeing you here after ZenFone 2 and Redmi Note 4. Hopefully a KudKernel will be in the works(if not already).

Kinda off-topic, but well rebasing over CAF is a tough job...
