Will the AVR-S570BT damage the Alpha 8in Carbon Fiber 2-way?

No. Without Dolby Atmos or DTS:X decoding, the AVR-S570BT simply has no height channel to send to the Alpha 8in Carbon Fiber 2-way.

What impedance setting should I use for the Alpha 8in Carbon Fiber 2-way on the AVR-S570BT?

None: the Alpha 8in Carbon Fiber 2-way is 8 Ω, and the AVR-S570BT needs no change for it.

Is the AVR-S570BT powerful enough for the Alpha 8in Carbon Fiber 2-way?

More than you need. From a seat 2 m away, loud 95 dB movie peaks take about 13 W per speaker, and the AVR-S570BT is rated 70 W per channel. Cinema reference level, 105 dB peaks, takes about 127 W.
