I'm not sure we can, even if we try. At least not for any practical cost. Canada has been trying to curtail, and ideally eradicate, rabies from the wild for the last ~50 years. Rabid animals are systematically culled. There's an oral animal vaccine. There's an ongoing vaccination program where they scatter the vaccine all over the place in edible treat format. The ongoing cost of these programs is considerable, running to hundreds of millions of dollars.

And yet rabies has not been eliminated from the wild. Not by a long shot. The cumulative effect of these programs over the decades is to mostly eradicate it from inhabited areas in foxes, raccoons and other species which are prone to human interaction. Actual eradication of rabies in the wild in North America, is essentially unattainable, even if we scaled current programs up massively. Too many skunks slip through the net. Unless we're going to simply sterilize the outdoors, I'm really not sure we could eradicate animal reservoirs for COVID-19.
