If the policy is set to restricted, then by design it’s blocked. Translation, your enterprise has decided it does not allow PS scripts to run on these systems and your security team should be able to tell you why this setting / policy is in place.
What you are asking, is to provide you a way to skirt this enterprise policy, which sounds rather, well, sketchy.
It would be more prudent for you to ask that this policy be changed to allow you to do what you are after ranter than working to skirt the policy.
All that being said. There are several ways to have PS scripts execute by setting the execution policy per session (meaning the policy is only active when you run the script and not affecting the host default policy). This is called ExecutionPolicy Scope and those are all fully documented in PS help files.

You have to user the scope when you ask PS to run your script. Again, I say, it is still prudent for you to ask about this before accountabilities are called into play.
