Love this solution but... when i use recovery mode I can’t csrutil disable. I get the command not found error. When in normal mode I can use this command but not execute it. It requires recovery mode. What to do?

Also tried the @Avaddon's solution, but when I reboot in recovery and tried the /usr/sbin/spctl kext-consent add XXXXXXX And I get the following output: /usr/sbin/spctl: No such file or directory What am I doing wrong? I'm on Big Sur 11.1.
