Increase the auto scroll speed in the carousel

Site URL: https://www.mauromaglione.com/xxx

Hi !
I would like to know if any of you know how I can do to scroll the photos faster, the default maximum speed is 1 second, I would like them to scroll at 0.6 seconds, and if possible I would also like to eliminate the fade between the photos.

Thanks so much for your help! : D
