I will give these free solutions a try

1) (demo version is free forever and apparently does the job):
SounSiphon

2) (controls via app or keyboard shortcuts, not via dedicated apple keyboard keys: F10-F12)

3) https://github.com/the0neyouseek/MonitorControl

Another fork that looks very promising:

...
You can use Karabiner Elements to use the default mac key (F1, F2 for brightness and F10, F11, F12 for volume) with this set of custom rules : Karabiner rules for MonitorControl
...
Bonus: Using keyboard shortcuts display the native osd
