Gigabyte's software is quite uncooperative generally and there have been reported RGB issues with the Aorus software with recent cards. I've personally had occasional issues with getting my Gigabyte 3070 to show up in RGB Fusion (on my old rig). Note that you may be waiting for a while to get a replacement getting the production problems, if you RMA it. I'd recommend not worrying about until such time as an RMA wouldn't leave you without a card for a month.
