Help with bootloader

[xMeth0sx]

Hi, I'm pretty new to the android scene, I've looked for a few days if there is a possible way to unlock bootloader on an Xperia M4 Aqua 2306, the issue is my phone has Bootloader unlock allowed = No and didn't actually find if there is an actual way to do this.
Found a few threads talking about how to unlock the bootloader but it seems from some posts that it's not possible to unlock, I was wondering if anyone could help me figure it if there is any possibility to unlock since my phone is quite slow and would love to breath some life to it, any help would be greatly appreciated!

the onli way i was able to root my 2306 was to downgrade with flashtool to lolipop the vertion 26.1.A.1.112 ...the onli one old enough to root with kingroot the onli app i found to root lolipop ....but then none of the tutorial i read got me back to the last update without loosing root and aving to deal with the 100 of preinstalled app .....tryed to let it at lolipop but the phone is now extremly sloooooow

was able to get to recovery but then after looking at all custom rom .....they all need to be install with fastboot and they all stated that you need unlock bootloader so i stop trying the phone is not realy worth it anyway
