Enable community plans while not allowing trial sign ups

[PPuserPP]

Is it possible to enable Community plans while keeping Trial sign up disabled. Both are part of the Internal consent plan and can't find any information on this specific query. 

Currently on the tenant we have got only Viral consent plans enabled and would like to enable users to be able to sign up to Community plans while not allowing to sign up to trial licenses or connect to a premium connector in an app and be offered for 30 days a free trial.

Thanks in Advance

If the user has a Power Apps Office 365 license assigned to them in your tenant they can login to Power apps and navigate to the following:

https://apps.powerapps.com/community/signup 

From that Web page they can sign up for a Community plan even if Trial signups have been disabled for your tenant.  If they try to go in through the regular Community sign-up they will be told they can't because Trials have been disabled.  But I validated that the alternate site does work even with Trials disabled.
