I am trying to control an LED driver using a PWM signal but unfortunately the Raspberry Pi Pico is using 3.3V on PWM and the LED driver specification sheet specifies 10V. What can I do to step up the signal?

You may not need an external power supply since the pin appears to have a pullup (guessing 33K to internal +10 but it could be something else).
It may be worth trying this:
simulate this circuit – Schematic created using CircuitLab
If it works, it will work in reverse (100% PWM = off).
