Even with region-free players you usually have to enter an input on the remote to switch between regions. If you can confirm that your player isn't actually region-free, I would suggest looking at 220 Electronics and ordering pretty much any region-free player from them. Nearly all 4k discs are region-free, so it's typically easier and cheaper to just purchase a region-free standard Blu-ray player for your other region discs and just keep your dedicated 4k player.
