Anything more will be due to a short circuit in the relay or wiring.
You can't adjust the current limit. It's fixed by the design.
Is it fixed by the chip manufacturer? What about the plot Vgs vs Id?
In case of short circuit the current will be 2A. If it is limited to 300mA, the PCB trace width can be reduced to considerable amount.
For 2A trace width required is 100mils (approx.), but 300mA requires only 10mils(approx).
