HI

I have the MM18 with 128 gb internal. I got a TB3 external 2TB drive running my boot Catalina and just installed Catalina and windows on the Internal 128gb ssd. I want to maximize space for windows in the internal drive and perhaps even giving 500 gb to windows on the external 2TB drive. I don't use the internal Catalina Mac OS. I just installed that to be able to install Windows 10 but Catalina is taking up almost half the drive. What are my options?
