Is there Any STIX format for external threat feeds via TAXII Protocol

[A.Faruq]

Hi Palo Alto Community,

Is there any documentation or configuration for Palo Alto NGFW that can be integrate with some external threat intelligence feed (via TAXII) to block any IoCs list? I need documentation for direct device, but if you have documentation using TIM in Cortex XSOAR, you can share to me. Now I using TIM in Cortex XSOAR to gather any IoCs from many source, but I think I need a documentation also to configure direct device if maybe.

Thanks
