I don't think that's a job for the frontend (XSane). The backend
should provide an option to adjust brightness/threshold for Lineart as
usually the variable threshold value is implemented in the scanner's

If the backend supports Lineart, it should allow to set a threshold.
Maybe you have disabled standard or advanced options in XSane?
