Idk, my 2020 is still giving one beep when the the truck is locked, and two when unlocking.
I've been able to disable or desensitize all the stupid nanny crap so I don't keep hearing all the beeping, and dinging when in traffic, or traveling on the roads here. I never checked too deep into trucks menu settings for that stuff your looking for, other then what I mentioned with the nanny crap. Other than that....I used the menu to do some minor changes in my trucks dash lighting. Sounds like you could have accidentally switched something off? Keep us informed when you find out what it is...I'm interested.
On another note, do your parking, and tail lights still flash when you activate your key?
