You can get Roon's DSP engine to use a convolution filter to apply room correction, see https://kb.roonlabs.com/DSP_Engine:_Convolution . I don't know if the Home Audio Filter plugins can work with Roon or not but Roon can apparently be used to apply room correction. I haven't tried it or heard it in use so I can't comment on how effective it is.
I can see 2 possible problems. First, if you do this in Roon it will only work for music you access with Roon so music stored on your own server and streaming services like Tidal which you access with Roon. It will not work if you're playing music from other sources such as a CD player or turntable, or music from a streaming service accessed outside of Roon. That may not be a problem if Roon is the only way you access music but if you play music from other sources you're going to need some other method of applying room correction for those other sources. The other problem is that digital signal processing can be intensive for the computer running Roon and if you are also using Roon for other DSP tasks such as changing the resolution of music and/or converting DSD to PCM. adding room correction to the mix may prove too demanding for your computer. I don't know how intensive the processing for room correction is on its own but even that might be too intensive for some servers running Roon.
Even if you can do it, the results are going to be dependent on the quality of the software filter you use and that filter will only be appropriate for the specific speakers, speaker location, and listening position for which it was created. Change speakers, speaker location, or listening position and you will need a new filter. I think that if you change from using SAM to not using SAM or vice versa you will need to create a new filter because of the change in the phase response below 150 Hz which SAM introduces.
My reservations don't mean that I think it's not worth trying. I'm just trying to make the point that there may be limitations to what you will be able to do and I think you should be aware of them before you start to try any form of room correction or acoustic treatment, whether it be physical acoustic treatments or digital correction. I use physical acoustic treatments in my room and I have to adjust their placement if I change my speaker position or listening position. Changes in speakers may also require changes with physical treatments. No room correction method is ever completely "set and forget". All room corrections relate to a particular speaker/position and listening position arrangement and changes to those givens require changes to the correction.
