ADSP-SC587 : Pin Muxing query -is unused PTP pins available for other muxing interfaces ?

Hello, 

We are planning to use the RGMII (EMAC-0) interface without PTP features. 

so, is it possible to use these unused PTP pins for other interfaces as per the muxing table?  

Please confirm. 

Thanks and Regards
