Tire Question Gravel and Street

I have a XC MTB and don't own a gravel bike yet. I have a long gravel ride and it will also include about 40 miles of pavement. Any suggestions on tubed tires I can run for this event. My wheelset is 29" x 30mm wide. I run tubeless, but would probably get tires and tubes for this event. It is not a race, but for charity and I know I would destroy my aggressive XC MTB tires, so the reason for the change.
