As u/astrokiwi mentioned, the maximum resolution achievable by modern or near-future groundbased optical telescopes comes down to about 5-10m. Depending on the lander used this would be anywhere between 1 and 5 pixels of lander visible in the image. The Lunar Gateway might be a different story however, as it will be large enough that such a telescope might be able to discern some of its structure.
