Before you can install it, you will need to unlock the bootloader. There are no officially supported ways of doing this, but there is information on the net. Follow those guides at your own risk - I have not tested them
TWRP Recovery available here
I am not in a position to support this ROM as I don’t own one of these devices. If you do flash it, please give some feedback here, If enough people find it works, /e/ may be persuaded to make it an official device
