Multisite activation on certain sites only

Hello,

I have an active WaaS Licence installed on a multisite installation where I host client websites that I design and build for them.  Some of the clients use the plugin for minor content updates, but most do not use it at all.

I would like the option to enable Brizy on only some of my client sites on the multisite network while using other page builders on other client sites (without the Edit with Brizy button on the edit page section).

Two questions... 1.  Is it possible to do this with a Brizy WaaS License?  2.  Could I do this with the regular WP Brizy Pro license since I am building the site for the clients and they are only using the plugin for content updates?

Please advise.  Thank you,

John
