Hello Frederik,
Yes, this is possible and the steps are documented in this article: https://learn.microsoft.com/en-gb/archive/blogs/virtual_pc_guy/allowing-non-administrators-to-control-hyper-v
Other option is surely by GPO but never tried before:
In theory from Computer Configuration –> Preferences –> Control Panel Settings –> Local Users and Groups; Add a new rule (New -> Local Group); You can use the Hyper-V Administrators Group to add members there.
Hope this resolves your query,
Best regards,
