Getting a build of optee android and tf-a to work on hikey960 in 2024

Hello, I’m researching some things about tf-a and the hikey960 is my main tool. However, I haven’t been able to get anything to build. I know its around end of life but if anyone has a reproducible build for optee, android, and tf-a that works on the hikey960 I would appreciate it very much.
Ive tried several old guides Ive found, like:

(Im unable to post more than one link so Ill pastebin the links to the different guides Ive tried following) https://github.com/ARM-software/arm-trusted-firmware/blob/c7d5e45d8f197ea0e276 - Pastebin.com

My main goal is to be able to tweak tf-a and optee for the device, and boot any version of android, although linux would also be fine. Mostly I just want to research this devices generation of trustzone.
