How to suppress room modes: brutfir?

Dear fellow audiophiles,

I’d like to get rid of a nasty room mode in my living room at around 32Hz without putting up some “nice” sound insulation stuff. Is there a way to accomplish this with Volumio? Is brutfir the way to go? Is there some instruction? I’m currently on Volumio 3 free & willing to upgrade to a payed scheme if required.

Thanks for any support,
Best, Holger.
