Visa on Arrival in Shenzhen if you already have a double entry tourist visas

Greetings,

I’m an Australian passport holder who currently has a double entry 30 day China Visa.

I’m just wondering is it possible to enter SZ on a Visa on arrival without triggering my double entry visa? I only plan to be in the city for two days, and have already used up one of my entries so far. The second entry I wish to utilize next year with my family.

Many thanks!
Regards
James
