This firmware is already available via Linux Vendor Firmware Service (LVFS). So one can easily install it using fwupdmgr. I did this in Fedora 33, and one thing I noticed about this update is that the computer wasn’t requested to reboot after the firmware update process is completed. So make sure to manually reboot the machine yourself to have this new firmware installed on reboot.
