Specifically the connector at the end broke so the hose is floppy. If I can remove it by hand (I can reach it by hand), I could replace the hose without having to take the intake manifold off. I plan on reworking the entire cooling system, but now is inconvenient for me. Was planning on doing that in ~30k miles. I see form the pic I could conceivably reach the clip. If I can pull the clip off, I should be golden.

Is there any particular brand that isn’t prone becoming brittle and breaking like the OEM hoses are?
Part number 64218376999 is the hose that connects to the hard coolant line under the intake manifold. The other end of it uses a hose clamp and connects to the heater valve control valve.

Part number 64218376153 connects directly to the heater core on the firewall and goes to the expansion tank/bracket.

Both hoses can be replaced without removing the intake manifold.

As far as the plastic coolant lines, genuine bmw is the best option. There are other manufacturers that make them out of plastic but they don't fit/seal well to the engine.
