SharePoint Online Administrator

Question

We are going to SharePoint Online. There are different SharePoint groups that want SharePoint access to only their SharePoint sites (they have their own domain). Is there anyway to restrict what a SharePoint Administrator sees? Possibly by domain? We don't want SharePoint Admins. from other domains in same company seeing other same company domains. Thanks,

No, a person who holds the SharePoint admin role can see all SharePoint sites and grant themselves full control of any site. In addition, a single M365 tenant only has a single domain (tenantName.sharepoint.com).

If you're referring to sites, each site is a permissions boundary, so for example, you can grant HR personnel only access to /sites/HR and Finance personnel to only the site /sites/Finance, etc.
