They can triangulate the signal, but in this case it has absolutely no connection to you or your identity, so you don’t need to. Regularly changing esims (IMSI) and IMEI will effectively neuter triangulation. You’re just a random red dot with no name.
Meh, the pixel 6a is pretty cheap. Warranty and creature comforts are for the daily driver.
Edit: I should add, there are a few mobile hotspots that officially support changing the IMEI
