How do I counter Peregrine Greaves in PvP?

Pretty much what the question says. I’m a decent player but certain builds I seem to not know enough of how to counter. Can anyone tell me how to counter Peregrine Greave titans one shotting you? I usually do PvP on my Hunter and enjoy fusions(I can toot my horn based on my gameplay and the compliments from teammates I’m Goated on fusion rifles), sidearms like rat king, trespasser, and I’m learning to use shotguns currently using imperial decree but open to more meta shotguns. I’d love to hear some feedback on this topic.
