Totally agree with this. A little MTB experience will really help. I first started riding an old hard tail MTB years ago on rocky, rooted trails that would get loose and dry in summer. I learned to get up out of the saddle, lower the center of gravity and pick my lines. All that helps with Gravel.
Also agree with the lower pressure. Finding the sweetspot will vary with tire/wheel combo, rider weight, etc. but there is a psi where you can avoid pinch flats and have a much smoother and faster riding experience by letting the tire conform to the surface.
