Probably a dumb suggestion for a technical reason beyond my purview, but what about a purely aesthetic solution where all instances of "TFA" in display and documentation of the module are a text variable in /admin/config/people/tfa that is "TFA" by default, but if there is text in the field, it will update all references to the entered string.
I think the semantics debate is endless so if your target audience is fine with "TFA", leave it blank. If your users prefer "MFA" or "2FA", enter that. If you need a more verbose description, "Two-Factor Authentication (TOTP)". This would then apply to the tab name in the user profile and all the setup pages that reference "TFA".
#13 also worked for me: PHP 8.2.15, D10.2.6
