Is there a 10X probe compensator BNC, but with out the probe?
Yes they exist and are called "BNC feed through attenuator". They usually look similar to the one in the image below. Depending on the specifications (impedance, attenuation, power, bandwidth) they range from bit expensive to bizarrely expensive. Most common type is the 50\$\Omega\$ feed through termination, but there are all sorts of variations with set attenuation.
