Solution 1:[1]

Drupal 9 Supports PHP 7.4 but the recommended PHP version is 8.0 or higher recommended. Check below documentation for a clear idea.

Drupal - PHP requirements

You can disable update notifications by disabling the Update Manager module, which is responsible for checking and informing about available updates.

Navigate to Extend -> Search for "Update Manager" and disable the module.

Disable Update Manager module

This is not recommended but you can keep this module enabled in your development environment and know when a security updates are released.

Drupal 10 is around the corner and it only supports PHP 8.1 and above. You should better migrate to a different hosting provider as soon as possible.
