Change boot order when dual boot on same disk drive

Hello everyone.

I've just installed dual boot Hackintosh and Windows on my PC on same disk. I install Hackintosh first, then install Windows. When I turn on my PC and it go to Opencore boot picker, it prefer Windows first. But I want to prefer Hackintosh.

How can I do to change this priority? I searched around and only found solution to set default boot disk. But both OS I installed on same disk.

Here is my PC specs:
- mainboard: aorus B365M elite
- CPU: Intel core i3 9100F
- GPU: RX 580 4G

Thank you so much!
