FCU and EPL lever
Personally I wouldn't risk it,id think you would get better performance making sure you were clean,torque maxed out(if i remember it can take 2400 for 20 seconds but been long time since flew one) prop fully forward and maybe chuck ignition on too.
I had FCU failure on the ground at startup once it just threw extra fuel in ,that just got spat into the exhaust and smoked everywhere.I would guess you have higher chance of compressor stall/flameout without FCU not to mention cooking blades and having them spat out too.
Where your flying now my best advice would be weigh everything yourself to make sure your never over weight(less surprises after takeoff) and always wait for good gap in weather before leaving.
Stay safe
