in whatever way to understand if .htaccess is enable? I am unable to browse the httpd.conf file during my shared server.

I've access through ssh. My host company uses cPanel Faster.

How about just placing a .htaccess somewhere which alters some readily-observable configurations and appear when they have been been transformed or otherwise?

Try uploading an example .htaccess file (e.g. having a single simple redirect rule) and appearance whether it works.
