I can confirm that it works with no issues with UEFI. I recently replaced R9 270 by RX 480 and it even worked with not issues after I forgot to update/remove the old ROM file for R9. Here is my command line. It uses a few variables for multiple GPU but you should get the base picture. I have both Windows 7 and WIndows 10 VMs and all of them work fine.
