Remove Video option from Talk

Hi all, apologies if this was discussed here before but using search I couldn’t find anything.

Since using Talk video option with more than 4 users is cost prohibited I would like to completely remove that option from talk, and use it only as a text chat.
(I already have Jitsi Meet woking fine and as a link using the “external site” app )
Does anyone know if it’s possible to do this?

Thank you!
