Hi, yes, from the center or any other location.
The easiest way to do that is by using the "origin offset" coordinates, it's the
ox,
oy parameters found in either the love.graphics.draw() function where you manually set them, or when creating/modifying a Transform object (see the docs for love.math.newTransform for more) and using that Transform with the overload of love.graphics.draw() that takes it.
Read pgimeno's in here for more:

These ox,oy values work like a convenience for pre-moving the object to the origin before applying rotation or scale to it, but you still need to set an x,y so the object is moved back where it should be.
(For curiosity, you can manually do the same effect of ox,oy by doing a sequence of operations on a Transform
like explained in this.)
