Of course, you can use USB_OTG1 port as Host only and USB_OTG2 port as Device only. In that case, you have to configure USB_OTG2 port for Device only mode, refer to the Section 4.10 of the attached document for the information on how to do that. Also, check that USB_OTG2_VBUS voltage is present during the Device operation.

Have a great day,
Artur
