Use Fritz Modem 5530 in combination with Otrbi RBK53

I am thinking to move to fiber glass cable to receive internet & TV siugnals.

I am reading however that modem i wil receive ( Fritz 5530) cannot be set into bridge mode, in my understanding however this setting ( bridhe mode ) is needed to be able to receive signals via Orbi.

Can somebody comment to my understanding and advice if i a am right or wheter it is possible to use hardware ( Fritz 5530 and Orbi RBK53 together)
