Always-on USB support?

I have a USB-A expansion card, and was hoping that there would be support for it to always be delivering power to a plugged in device, even when the laptop is suspended. Is there a way to enable this functionality, either in software (I’m running Fedora 34) or in a future bios update? I find this feature very useful for charging my phone on my Thinkpad X270, for example.

I think if the laptop is plugged in, it will still supply power to the USB ports (not sure), but in my experience, it does power-off the ports after a while in suspension on battery power mode.
