Logic - updating information about audio unit plug-ins

I downloaded the 90-day demo for Logic Pro. Every time I open Logic, Logic initiates "Updating information about audio unit plugins".

The problem is that I've installed demos for many plugins. So I get popup after popup saying, "Can't identify license for __ plugin" (these plugins are all expired demos). To close each of these popups takes 30 minutes.

I don't care about these demo plugins working. I just want to be able to use Logic's other features.

My Question: Is there any way to get Logic to not try to use certain plugins when Logic initiates?

You might be wondering why I don't just trash expired demo plugins. That's actually a separate issue. I don't know where they're saved and they're probably in many folders. So any guidance on that would be helpful as well (is there a way to identify from within Logic where expired demos are located and maybe even to delete those demos)? Additionally, there are expired demo plugins that I thought I did trash, which Logic is still trying to validate for some reason.

So again, the primary goal is to get Logic to not try to use certain plugins.

Thank you very much for any support.

Edit:

Figured something out right after posting. Many of the plugins were from Soundtoys. I had downloaded demos for the whole Soundtoys suite and they all expired. I just figured out how to uninstall those, which helps things enormously. Logic initiating is only taking a few minutes now (still delayed by popups for other demo plugins I don't want). So this was a fortunate discovery. But I remain very interested in answers to the questions though. Thank you again.

Another Edit:

And I may have just found the solution for that first question. In the plugin manager there's a button to "Disable Failed Audio Units". Will press that now and hope it works out

Edit:

Nope, that's not solving it.
