External drive is greyed out in Time machine options to exclude from backup

Hello guys, in sequoia I use a Mac mini m2 and boot from a samsung T7 HD without any problem. I use Time Machine since years ago without any problem now, I want to exclude from backup the "Macintosh HD" (the original internal Mac mini hd) but in Time Machine when I try to choose this HD to exclude, it appear grayed and I cannot exclude. What could be happened? I tried everything but without success... thanks Simone
