Is your feature request related to a problem? Please describe.
Reviewing the circuit, I realized that all peripherals, such as fans and TMC drivers, are using the direct power supply from the 12/24V source, with only a fuse limiting the current.
The reverse polarity protection circuit does not protect the drivers or the fans in the case of reversed power connection.
It is true that the diodes present in the circuit (S1A and S1G) would not be able to handle the high current of the TMC drivers, especially when they are operating simultaneously.
Describe the solution you'd like
Since this is a circuit that many people without knowledge of electronics may purchase and make incorrect connections, or even connect it wrong, I believe it would be a good idea to implement a reverse polarity protection circuit to protect the power supply for the TMC2209 drivers and the fans.
Describe alternatives you've considered
Replace the existing diodes with ones capable of handling the full current demanded by the circuit, assuming maximum load.
Use an N-channel or P-channel MOSFET for the implementation of this circuit
