Hello @Federico Coppola ,
Thank you for posting here.
After my research, I cannot find such GPO settings to add link to "Quick access" or in "This PC".
Maybe there is no such existing GPO settings to acquire your request.
For your request, we can try the following similar method.
You can Pin the local folder under Quick Access.
Or configure Drive Maps for the folder you want to share through GPO, so that the user or computer can access the file through this path on the interface shown in the following figure (in my lab, the folder is configured with drive mapping for folder redirection.)
By the way, What link do you want to add under “Quick Access” or “This PC”? In order to better troubleshoot this issue, I would be honored if you can provide more details.
For more information we can refer to the links below:
