[Mi10T Question] What's the best procedure to install this ROM as april 2021?


Feb 2, 2018
Hi, I'm thinking of switching to this ROM on my Mi10T but, I can't find a straight procedure to install it, some say to wipe this and that, reboot, install, wipe again, others say to just boot twrp and not install/flash it and wipe with stock recovery.
So I would really appreciate if someone could guide me to install this ROM
My main concerns is losing Widevine L1 certificate but I think if I follow the correct process, nothing bad should happen
