Latest Form plugin not compatible with ver 1.7

Running the latest 1.7 versio, the system proposed an update for the form plugin.

After upgrading, the admin panel doesn’t display and on the main grav CMS page I’ve got a popup saying Composer detected issues in your platform: Your Composer dependencies require a PHP version “>= 8.1.0”.

I’m still using php version 7.4 for other reasons than Grav. Any possibility to revert to the earlier release of the form plugin ? Or make a release working with php 7.4, or doing a check to not install if php 8.1 is not available (for others, its too late for me) ?
