Have a look at the chemacs2 package
https://github.com/plexus/chemacs2.git

With this package, you can define multiple Emacs profiles, making it
easy to start Emacs with different configurations or package
versions. For example, I have a number of different profiles, including
'default', 'experiment' and 'vanilla'.

My default profile is my normal day-to-day emacs configuration.
The 'experiment' profile is where I am trying out different packages or
different configurations. When there has been a major new release of a
package I rely on (such as org), I will usually upgrade in the
'experiment' profile and try it out to verify it has no major issues
before I install it in my default profile.

The 'vanilla' profile is a very basic and as close to 'out of the box'
configuration as I can do. I use it when I've discovered a bug and want
to both verify it isn't due to any of my configuration and provide
a minimal reproducible case which works with Emacs default
configuration.

All I have to do to use the non-default profile is start Emacs with the
command argument --with-profile=<name> where <name> is the profile name
I want to run.
