SK-TDA4VM: M.2 M KEY how to select SATA or PCIe when PEDET pin floating state?

Part Number: SK-TDA4VM

This is schematics of SK-TDA4VM which PEDET pin has no connection. 

I wonder if SK-TDA4VM could select PCI-E or SATA for inserted device on M.2 M Key slot. 

 

Can we select M KEY device to use PCI-e or SATA interface with Z-state on PEDET pin (floating state) ? 

Similar question, is there a way to select PCI-e or SATA when M KEY device is insertedby setting i2c,  for example?
