not really sure how well these options would work but i'd try...

turning the bass amp away from the drums. so that the sound is projected against a wall or into a corner of the room.

you could also try taping a piece of cardboard under your drum to cover the snares but that might had a negative effect on your sound. maybe just a piece of paper towel even, you just need something to absorb the sound wave coming from below your drum without interfering with the sound wave projecting from your own hits. it doesn't have to be tight on the snares but it would have to touch them.

i'd definitely try pointing the amp a different direction first though.
