With the Rideable Mobs data pack you can ride any Minecraft mob. True, it will not be possible to derive any benefit from this, since the control of such mounts is not implemented here, and they will move at their discretion. After installing the datapack, you need to call the command line, type /function passive: %mob_name% or /function hostile:%mob_name% to call the desired mount NPC. In the first case, they will be neutral to all, and in the second, they will have standard characteristics.
