I also checked out the instructions on mass deployment of Fusion found here: https://kb.vmware.com/s/article/2058680

The instructions do give some flexibility in installation location, (unlike the default installer which wants to install in /Applications)  but don't seem to negate the need to run as admin for an initial setup. I just tried using it to install Fusion in an alternate location (which did work) but it still asked for an admin password for initial setup.
