Module development and code questions

Hello I am writing a custom distribution. This distribution contains many modules, some of them I have set to be activated while the distribution is installed, and others it just installs but does not activate. I would like to add one or two pages of forms where you can select which modules to activate. I know that for this I can create the forms in the src/form/install folder and then in the .intall file specify what to do with the form data. But I don't really know how to do it. Can someone give me some tips on how to do it?

Thanks in advance.

}
}

Hello everyone, I have been trying to find why when creating a taxonomy from a controller in submit of webform module it stays in that process and does not respond until the timeout expires, but if it creates the taxonomy without a problem, as if after creating it it stays in an internal loop

I've searched here and in the modules and I was wondering what would be the best practice to achieve the following:  we have a  multisite installation of drupal 9 with different subdomains based on clients persona.  I'm setting a cookie to remember anonymous visitors choice's of persona and redirect to the appropriate subdomain.  I can see a couples of ways to do it but i'm curious to read about your's.

Thanks a lot,
