While Marcus’ response is certainly correct it does little in providing a practical answer to your question.
I use an X310 with TwinRX daughterboards and have found that it is inadvisable to use input levels to the TwinRX daughterboard greater than -30dBm because higher levels than that tend to result in distortion/compression issues. I don’t know what the damage threshold is for the input ports on the TwinRX daughterboard. For my radio astronomy applications I use an input level of -60dBm and that seems to work quite well for me. I don’t know if other daughterboards for the X310 have different input-level behavior. Perhaps this response will give you ball park answers that you can use.
