You cannot. It is one or the other.
Also, your original request did not include this:
i want disable .htaccess for all hosts,
...
i dont want it work on my server
It is probably possible to give another <Directory "/pathtodirectory"> option to allow AllowOverride, but I didn't test that option, since it wasn't what was asked.
Edit: So, upon testing, this works:
Code:
<Directory "/">
Options All
AllowOverride None
</Directory>
<Directory "/home/username">
Options All
AllowOverride All
</Directory>
This would again need to be distilled, Apache rebuilt and Apache restarted. The
username in the path would need to be revised to the actual cPanel username. At that point, the account in question can have an .htaccess file working.
