Hi @DimaTabor ,

Check out BIOS of your 7050 and see if options described in the following article exist:

Dell - How to boot to an external device using USB TYPE-C connection

Besides, you probably know it already but just a reminder that OTG require certified USB drives. Check out warning from Hardware considerations for Windows To Go:

"...Using a USB drive that has not been certified is not supported."

And I cannot located any drive listed above in USB-C interface. You may then need a USB-C to USB-A cable as workaround.

The 7050 is not an android Phone so no OTG is not supported.

USB OTG is a hardware and software standard for smartphone or tablet through the USB Type-C

A pc is not a tablet or smartphone.

UEFI Bios does not accept OTG commands via the USB ports.
