Can't check on your NUC. On NUC8i7HVK however, setting Portable Device charging mode to Off, disconnects the power from the charging USB port (yellow) in S5 power state. In order to disconnect power in S5 from all other USB ports (blue ports), the parameter USB S4/S5 Power in Power tab should be unchecked.

Lets see if some user with NUC8ixBEx may confirm your findings. If yes, the problem is in BIOS.

You want to say that you needed to uncheck the DEEP S4/S5 (disable)? FYI, the Portable Device charging mode = Off is working in my NUC with DEEP S4/S5 disabled.
