Exec() has been disabled for security reasons

Hi, every one
i have a problem
I do dump for database and this warning message appear to me
Warning : exec() has been disabled for security reasons in /storage/ssd4/381/7547381/public_html
I searched for it
the suggested solution

In order to eliminate this error message you need to do ONE of the following things:

Remove the exec string from the disable_functions at php.ini* file
Ask your hosting provider to remove the string above if you don’t have an access to the php.ini* file
Change hosting provider which allows the running of the exec function.

I need help in this
thanks

Can’t do any of those on free plan sorry.

Well thats a lie.

You could do the third one.

Change hosting provider which allows the running of the exec function.
