Lightroom to Denoise Changes L/R import settings?

Hi, use L/R 6 with Topaz Denoise when I import into L/R I use my own import setting so L/R does not impose any noise reduction etc when I send to Topaz denoise and return to L/R then L/R imposes the Adobe settings that I cancelled out with my own import options is there a way to stop this happening? Hope question is understood. Thank You, Russ.
