The Pi Pico datasheet recommends a maximum power draw on the 3V3 pin (pin 36) of 300mA. However, the RT6154B datasheet indicates that up to 3A can be drawn when Vin > 3.6V, which is the case when powering the Pico from the USB connector with a 5V/3A power supply. I am considering a design where I would draw around 1A on the 3V3 rail. Should I use yet another power converter or can I safely draw the 1A from pin 36 ?

You can safely draw the suggested 300 mA.

I don't know what damage you will cause to the traces if you draw more. To find out you will have to ask the board designers.
