Seekbar & Navigation

I've almost completd my first project. When viewing my slides in Engage, I utilized most of the templates provided. These templates offer automatic navagaion buttons. i.e Next slide etc. I don't want to confuse my viewers by having those two navigation options since next and back is also provided on the seekbar.

Therefore,some slide offer both. I decided to have my presentation so that all slides are advanced by the user, so maybe I don't need to include the seek bar and just add my own next and back buttons on the slides that don't use engage? Any advice?

Thank you!!!
