Full time 4wd

I'm getting a 1982 J10 74k original miles 360 2bbl. I am a jeep nut with many wranglers under my belt. Not mechanical so here's the question. It has factory full time 4wd with the selector switch for 4high to 4low driver side seat area. Guy has put lock outs on the jeep. Is this an issue for me as I understand it's fulltime. If I don't have the lockouts "locked" will this cause damage or better that it can free wheel and have 2wd option? Thanks
