VST equivalent to DR18 voice isolation ?

Hi, giving Davinci Resolve Studio 18 a spin and i’m baffled by the results of the “voice isolation” option in the fairlight tab.
I do have the free Accusonus VST bundle which I’m extensively using in audacity, but nothing comes close to the DR option.
Anything that would come close to it ?
Basically it’s for isolating a speaker’s voice in a noisy classroom.
