DWM1000 Sync Pin and EXTCLK Access

I am currently looking at building a TDoA system that has wired synchronisation between anchors (from https://www.decawave.com/wp-content/uploads/2018/10/APS007_Wired-Sync-RTLS-With-The-DW1000_v1.10.pdf).

Would it be possible to implement this scheme using the DWM1000 (instead of starting with the DW1000 from scratch)? In other words, could I bypass the DWM1000 clock and drive the EXTCLK pin on the DW1000 (pin 3 on the DW1000 in the DWM1000) with my own clock signal AND could I also use the SYNC pin (pin 4 on the DWM1000)?
