Increase Vram from BIOS and Hub usb-c

#1
Hello. I would like to know if I can increase dedicate vram from BIOS.

Also, what kind of hub do I need for charge minix and give output video from USB-c simultaneously since I can't charge it from my portable monitor. I would like one cable or hub for charge minix, charge monitor and send video to this monitor.

Thank you much.
