Custom NEXT OR PREVIOUS Buttons to appear at certain times on slides? EMBEDDED WEB OBJECT FORM

Is there a way to create a specific time when the NEXT or PREVIOUS or SUBMIT button will appear? I am asking because I have a questionnaire I embedded into the training (MS FORM) and I wanted to ensure that learners were completing the questionnaire as to not bypass it.

Any suggestions? I've already thought about putting a time limit on that slide as  it's really short questionnaire, but I dont want to take a chance that someone will have their phone ring or something else to take them away from it, and then when they come back, the slide has progressed.

If the "next" appeared after a certain point, that would help reduce bypassing from happening so soon. If they see NEXT as soon as they get to that slide, it might be  more tempting to bypass.
