How to delete macOSInstaller from boot picker after an unsuccessful update?

I was tryin to update my Hackintosh to Sonoma 14.6 Public beta 2 from Sonoma 14.5 but I can't seem to complete the update. It boot loops in the macOSInstaller. But that's not the problem, I don't want to update anymore, I can boot to my 14.5 OS without a problem, but there is a macOSInstaller boot in my boot picker. I assume it's for the update that was never completed.

how can I delete that boot option? it takes up 10GB in my SSD.
