My Apple Account disable on my iPhone

An Apple ID being "disabled" (If your Apple Account is locked, not active, or disabled - Apple Support) is not the same as it simply being greyed out on a device. Your post is a bit misleading in that regard.

If an app or feature on your device is not working, not appearing, or is restricted (grayed out), a frequent reason is it may have been disabled using Screen Time, or by an IT administrator if you are using a device owned by an employer or educational institution.

- Read this support article If your Apple ID or other options are greyed out in Settings —> If your Apple Account is grayed out in Settings - Apple Support

Tap Settings > Screen Time > Content & Privacy > scroll to Allow Changes and turn on.

- If the device is managed (Settings > General > VPN & Device Management), contact the IT department that is doing the managing.
