How to Ensure the macOS Virtual Machine is completely isolated from my Actual mac (14.2.1)

Hi All,
I've read this following link: https://kb.parallels.com/128842 .
Unfortunately, I do not believe it tells me clearly if there is a way for me to ensure that the macOS Virtual is completely isolated from my actua mac.
Hoping if others here would be able to guide me through this. Currently, I don't even see a shared folder between the two which makes me wonder if they come out default isolated, but per the link it states the opposite.
Thanks!
