This message in the Wordpress admin panel is not critical and not required.
But if you wish, you can independently change the PHP version for your site to a newer version.
(after this, make sure that all other scripts and modules on the site work correctly. Sometimes they are not compatible with new versions of PHP).
Clients can independently change the PHP version for their hosting account.
You can also manage PHP modules and features and enable those that are needed for your site.
To change the PHP version, go to the CPanel control panel.
Find the "Select PHP Version" item and there you can select the desired PHP version and enable/disable the necessary modules.
If you do not have the "Select PHP Version" item in your CPanel (or it is not activated)
That means you have another similar module: "MultiPHP Manager"
Select the site for which you want to make changes, select the desired PHP version,
Save your changes.
After this you can make changes in the PHP settings (php.ini file)
This is done in the "MultiPHP INI Editor" item.
Settings can be changed for each site, each version of PHP.
