Is your feature request related to a problem?

Currently, we have the ability to set an entity visually on fire without it being actually burning
but the way visual fire works, it is not possible to disable visual fire if the entity is really burning

Describe the solution you'd like.

Internally, the visualFire field could use a nullable Boolean object and default to null and make the entity burn if true
not burn if false
and send the actual fire state when null
I understand this will cause problems with existing plugins that utilize this method, other suggestions are more than welcome

Describe alternatives you've considered.

Also, I would like to suggest adding a lockFireTicks method to be able to make entities burn or not start burning as long as the ticks are locked
