Double Menu bar - Remove the original

Hi to all.

I'm new to Parallels. For business reasons, using Mac I need to virtualize a VM (always MacOS), on which to run the VPN.
Everything works great and I'm very happy.

However, I would like to find a way to not have the menubar of the physical PC when I have the Virtual Machine in full screen.

Is there a way? on a windows VM just put the gaming mode, but on macos I couldn't find anything.
