Multiple small led or one big one
the driver specs are: output voltage 30-36 [V], 3000 [mA] ... The 10 [W] chips run at 9-11 [V], 900 [mA] ... so is this possible


No.

Not the way I understand the scenario.

You'd have to run three 10W LEDs in series to match the voltage but the constant-current driver then has the wrong current.

You really need to buy or build drivers to specifically match the LEDs or LED-modules you are driving.
