First I thought of Ra8+ but 1.Ra6 is quite better

It looks like the only chance is 1. Ra6 forcing the win of the Q for a R. 1Kf7 2. Nd8+ Kg7 3 R:h6 K:h6 4. Nf7+ and the N can beat the h-pawn to h1, e g 4...Kh5 5. Ne5 h3 6. Nd3 h2 7. Nf2 Kh4 8. Kd1 Kg3 9. Ke1. Lot of other variations are possible, but the h-pawn can't be promoted without decoying the black K to h1 to allow the white K to get to the e-pawn and free the d5 pawn to promote.
