Is it safe for the host machine to expose Parallels Desktop Host Adapter to the Internet

Hi there

I have some Web services running on a Parallels Desktop Pro Edition Version 16.5.0 (50692) running Ubuntu.

I have selected the "Default Adapter" in "Hardware/Network/Source" configuration - it then gives me a Dynamic/software Network adapter I can port-forward the local internet router to.

My question is then, is it safe for the Host machine(in this case MacOS) to open up to the Internet - that is if I set "Options/Sharing/Share folder" to "None" and deselect "Hardware/Shared Printers/Share Mac printers with Ubuntu Linux" ?

Thanks
