Sourceguardian in Cpanel without WHM Access

Hi,
I have SC installed in a Cpanel, an account without access to WHM.

Support does not want install ixed.8.1.lin because it is not yet available in EasyApache.

Is there a way I can set ixed.8.1.lin in my cpanel account without relying on hosting?

You can set it in the .htacess file within the folder where you want ea_php81 as the default programming package. Other folders can use other versions.

What should I write in the htacess ?
