RadxaCM3 more 3V3 current required

Hello there,
I’m working on a baseboard for the Radxa CM3. My application requires more than 600mA at 3V3. So I want to add a separate 3V3 regulator onto the board.
Is it possible to connect the VCC3V3_SYS with the 3V3 from the regulator? Any consequences for the power up sequence? Anything else I should consider?

Thanks in advance.

Kind regards,
Leander
