EDIT: I realized that I am maybe a little sensitive, and the question could be read the other way round, giving the liver enough time to recover between two occasional (small) intakes. That is actually an interesting question.

Leaving original answer (but please don't be triggered by me failing to read the question correctly):

And you're free to do so.

But don't expect an absolution from a health professional, in the form of a number that is "always entirely safe, under all circumstances".

Alcohol is essentially a poison for the body, which he can tolerate quite well in respectable amounts, compared to other toxins (we can actually "buffer" a certain amount AFAIK).

But talking about lesions in liver tissue growing back without scarring or long-lasting consequences is really out of the safe zone if you ask me. So your questions is clearly rubbing me the wrong way.

Also, sometimes your liver can be weakened or inflamed (without you realizing), and then obviously every drop counts.
