Optimize Disc

This is my first time on this Forum. I am running W10 with latest Norton Internet Security. I am a 20 year user/customer of Symantec/Norton products. With the current product one of the features is “Performance” and under that is the “Optimize Disc” function. I would like to know how to turn off the automatic scheduling of only the “Optimize Disc” function without affecting other functions. I can always schedule the function manually, but the automatic schedule of “Optimize Disc” is a performance hog in itself. I have one desktop and one laptop. Any help would be appreciated.
