I stand corrected 😄 Thanks for providing that information. I plan on installing the Merlin firmware on my GT-AX11000.
I've had the GT-AX11000 since January 2020, and remember seeing posts that Merlin firmware was not supported on the GT-AX11000, and wouldn't be supported. I do prefer Merlin firmware over the ASUS firmware. With the GT-AC5300, I was using the Merlin firmware and found it to be much better and more stable!
I'm currently without a GT-AX11000, as this is the fourth time (in two months) I've had to send it back for an issue with the 2.5G Gaming Port (failing to establish an internet connection to my Xbox Series X). This will be the third, brand new / factory sealed, GT-AX11000 Asus has sent me. Frustrating to say the least.
On a separate note, I've had NO ISSUES with using the latest ASUS firmware for the GT-AX11000. It performs very well. I'll be happy to share my settings once I get the GT-AX11000 back this week (hopeful).
