Usage of chipselect ce0 and ce1 for two SPI cards

Putting my hardware together, and have issues to get both card to be recognized…
Though one is input (UGreen DABBoard), and the other output (HIFIBerry AMP2).
UGreen documentation mentions the DOUT and DIN can be connected (physically) to have DAB audio on the HIFIBerry.
But I like the software approach to play audio from files/streams.
Googled and found chipselect CE0 and CE1 for SPI.
Is the AMP2 a slave or master? Being a slave it could be possible to use the slave select, and maybe update the corresponding drivers...
