Hello Greg, thanks for the reply to my post.
I think my critical issue may be lost in my long-winded first post. The issue I would like resolved is that there is no volume slider nor volume number for the Moon ACE in Roon. I don’t have the fixed volume issue.
From an older support post I saw this explanation from a Roon rep:

Hello @Audio_Vision,
The SimAudio Moon Ace is only capable of incremental volume control, and thus will not show it’s volume level in Roon.
We are planning to include a fix in an upcoming version of Roon that will stop Roon from showing “0” as the Device’s volume if it only supports incremental volume.

I am quite doubtful that the ACE only supports incremental volume change. I understand that it uses the same Mind2 module for streaming as the Moon 390. The Moon 390 has a volume slider and displays the volume level number in Roon (I have a 390 as well and have verified it).
Also the ACE current volume (set with Roon + and - buttons) is displayed accurately in the Mind app in IOS.
I think Roon should be able to interface with the ACE the same way it does with the 390.
