Regain your privacy! Adopt /e/ the unGoogled mobile OS and online servicesphone

You have to download the .zip from github

You can boot to custom recovery to install it,
Or you can flash it with fastboot command

The latest version of MAGISK only has an .APK file, but you just have to rename the extension to .ZIP to be able to flash it using a Custom recovery.

I can I start even with the bootloader is locked, fastboot boot twrp.img and flashing Makist.
is it possible unlock the bootloader?

Thanks for the informations.
