DISABLE Power on USB ports when turning off the PC motherboard Asus Pro Ws Trx50 Sage Wifi

[Willet]

Hello friends. I have an Asus Pro Ws TRX50 Sage Wifi motherboard, and I need to turn off the USB ports when I turn off the computer. This motherboard has BIOS, not UEFI, so I can't see where to disconnect the USB ports when I turn off the computer. If anyone knows, I would be deeply grateful. Thank you and best regards.

Hello @Willet ,

Thank you for reaching out to us.
Please set "USB power delivery in Soft Off state (S5)" to [Disable] in the BIOS. 
You can find this setting under Advanced > Onboard Devices Configuration, or refer to page 48 of the BIOS Manual.

Thank you.
