You would have to delete the M109 and the S number after it but that is the same as turning off the temp in slic3r.
If you want to set the temp automatically and not have it wait you should look in your firmware config for #define TEMP_RESIDENCY_TIME 15 // (seconds) and lower it.
Or
Set the temp to 0 in slic3r and then add M104 S190 (or what ever temp you want) in the start gcode (M104 is set temp but do not wait)
