Hi team,

Could you tell LM2903 series can support the dual-supply operation?

Yes. Connect the positive supply to pin 8, and the negative supply to pin 4. Use two decoupling capacitors between these and GND.

thanks for your question. As Clemens responded, it can support but please recognize that the output low level will be referenced to whatever voltage is applied to pin 4.
