Have you successfully reamped a soloed track via AES?
If you have the RME selected as audio device typically you should only need to go to the dry track's I/O settings, disable "master/parent send" then add a new hardware output and choose AES out. Switch Axe-FX to AES in, record a new track from RME AES in.

Not with AES

Using the RME ASIO driver, I have disabled "master/parent send" then added a new hardware output and chosen AES out. In the RME TotalMix Control Panel, I see the AES metered Input from the Reaper dry track. I see no Metering in the AxeFxIIXL.
As for the AxeFxIIXL, at the "I/O Audio" tab, I have selected
MAIN INPUT SOURCE: SPDIF/AES
WORD CLOCK: SPDIF/AES In (have tried both)
SPDIF/AES SELECT: AES
.

.
USB/DIGI OUT SOURCE: OUTPUT 1 (have tried all three)
In a new Reaper track set to Record, I have disabled the "master/parent send" and for the input, have selected AES.
I get no input showing on the AxeFxIIXL meter.
I have swapped the AES cables with the same result, so cables are fine.
The AxeFxIIXL AES-OUT and the RME AES-IN work fine.
So, for hardware, it appears that there could be a problem with either the RME AES-OUT or the AxeFxIIXL AES-IN
But I am hoping that this is an AxeFxIIXL software setting.
