Such a white dwarf cannot exist.
The reason is simple, and does not require any calculations or deep understanding of physics.
White dwarfs are incredibly dense, orders of magnitude denser than ordinary "molecular" matter, which means that the Coulomb force whose outward pressure keeps the latter within its characteristic range of densities must be completely overwhelmed by inward pressure (resulting from gravity) in the former.
In other words, close to the white dwarf's surface, the gravitational field must still be strong enough to keep it as dense as a white dwarf. Edit: The faster the star is rotating, the stronger the gravitational field must be in order to compensate. Such a gravitational field would also compress a human to the density of a white dwarf (edit: assuming that the human was trying to stand on a surface attached to the white dwarf. Staying safe in a fairly close orbit might be feasible).
The same reasoning shows that one cannot stay alive close to (edit: and stationary relative to) the surface of a neutron star or other exotic star made of incredibly dense matter, which includes stellar-mass black holes, but notably does not include the supermassive black holes which exist at the centres of most galaxies, and which are far less dense than these other objects (at least, if one counts their size as being given by the extent of their event horizon).
