It may be possible but currently there is no library that does that.
The controller used on the Mesh devices is rather short on hardware timers and almost all of them are currently used by the device OS.
While you can require access to some timers you’d have to sacrifice some features in exchange.
e.g. NFC uses a timer which could be obtained when not needed, but as it stands there is no high level API for that and you’d do that the bare metal way - that’s probably the reason why there hasn’t been a library contributed that would rely on exact hardware timing for these devices.
