Hi @itot
Thanks for writing in, we'll be happy to help out here. May I confirm, are you referring to the shared views which can be shared with select users? (as shown below)
If so then yes, you can either remove a user from that selected view by clicking on the cross next to their user, or you can use the *remove view* option to remove it altogether
If you have any further questions don't hesitate to give us a shout.
Cheers,
Andrew
