Does anybody know how to create a tick accelerator

I would like to know if there is any way to create a tick accelerator for both tile entity/block entity ticks as well as random ticks in a specific area, so no gamerule changes.  I know that it is somehow possible to change the tick rate of specific blocks because coded mods do it.  I am willing to use custom code or file manipulation if it will get tick accelerating working.  (Also I know that there is a procedure block that says something about tick updates, is does not work for what I want to do.)
