Sharing folders uses SMB v1

When sharing folders between the mac host and the windows vm, parallels uses SMBv1 from the early 90s. SMB version 1 send lots of extra messages and is less secure and efficient than modern versions, the current being 3.1.1. Is there a way to force Parallels to do sharing over a more recent version of SMB?

Thanks

Hello AllenH4, Please let us refer to the knowledge base article to share the files between Mac and Parallels virtual machine. Thanks.
 
GampaA@Parallels ... Could you provide a link to the specific help topic you are referring to? I just blindly searched https://kb.parallels.com/ for "share the files between Mac and Parallels virtual machine" and 100+ responses came back and I'd like to avoid spending all day going through all the results.

I'm having the same reported where I'd like to use SMB v3 vs v1 to access my Windows VM files from OSX to see if that improves performance issues I'm having.

When I run smbutil statshares -a in zsh I see the following indicating SMB_1 is used and I can't find a way to change this to SMB_3.
