Help with teacher recommendation requests on Naviance

I requested LORs from my math, science, and ELA teacher. Two of my schools need an ELA teacher LOR, all the others don’t. I already requested all my teachers on Naviance to send the request to all schools since I asked last year and didn’t have a list.

Can I delete my requests and re-request them on Naviance with certain schools? I would prefer schools that only allow 2 rec letters to only get my Math and Science, not ELA; unless the school requires ELA. Also, should I send a math and ELA or math and science? I’m going into a STEM major, but not sure if schools want a more varied rec profile.

Thank you!
