Can't disable System Integrity Protection from Recovery Mode?

Hi,

I need to temporarily turn off SIP (long story) on a MacBook Air M2 running MacOS 13.3.1.

When I boot into Recovery Mode (startup pressing power, options, pick account, authenticate, etc.) and try to launch the Startup Security Utility from the menu, it says it can only be run from Recovery Mode (which I'm in). I've tried launching the Terminal from the menu and using csrutil disable but it says the same thing (see attached)

Is there some other security mode that can disable one's ability to turn off SIP?

(I've been through Apple Support (regular, senior) who referred me to Developer Support (senior) who said it was beyond their scope and that I should post here.)

Thanks, Colin

I have done this at least a dozen times over the last couple of months but, for some reason, today it worked. ¯_(°-o)_/¯
