Can supplier registration be created without a site

Summary:

is it possible to register supplier without any site?

Content (required):

I have another integration that creates the site and get the correct bank and site information on the suppliers after supplier reg. approval.

If I could make sure that supplier registration never created a site, (but only supplier info and address and contact) that would be great.

In "Configure Supplier Registration and Profile Change Request" it seems like I only can choose not to auto create site assignment, and not, not auto create the entire site.
