Disabling gpu (mount -uw /)

When i installed mountain lion i could disable nvidia gpu through single user mode but after updating to Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina i knew it will reset this config so i went straight to single user mode but its giving me error that i cant mount Disk cause its read only after few seconds its spamming You shall not pass! I need to disable this nvidia gpu to make it boot normal.
