Nope.

Discord sometimes flags your whole account to require a phone number.

It's not a "server"[sic]-specific requirement that can be disabled somewhere; it's an account-wide requirement that cannot be disabled unless you open a support ticket and pray that the person in charge of your ticket is not having a bad day.

I might have gotten unlucky with my ISP, but Discord blocking me from doing anything at all unless I give them my phone number, is what made me leave it once and for all.

Oh but without deleting my account, because I can't delete the account unless I give them my phone number.
