Puck.js firmware can be built for SDK14 which does support Bluetooth 5, but it hasn't been tested enough so far, and in this case I don't think it will help you.
The longer range is achieved just by slowing down the transmission speed, not by boosting the power in any way - but then I believe the slower transmission is only readable by bluetooth 5 devices, and not any older ones.
What device are you using to read the advertising data? It may be that something with a better aerial will give you significantly better range.
Also, have you tried
NRF.setTxPower(4)- which will increase the transmission power.
