The constraint here is maximum depth of field, and the hyperfocal distance is how you get it for free. At 10mm and f/8 the hyperfocal distance is only about 0.64 m, so if you focus at roughly 1.3 m — a rock or bush a step or two in front of you — everything from about 0.65 m to infinity falls acceptably sharp. Set aperture priority at f/8, drop ISO to 100 for the cleanest file and the most dynamic range, and let the foreground anchor the frame.
Watch out for stopping down too far. It is tempting to reach for f/16 or f/22 “to be safe,” but past about f/11 diffraction softens the whole APS-C image, and you lose more sharpness than the extra depth buys. f/8 is the sweet spot; focus deliberately rather than closing down to hide a lazy focus point.
