I think that Joe W is right, there are no pre-pass hands that can guarantee a shooting the moon. However I think there are hands that guarantees shooting the moon unless the distribution of hearts is extreme AND a villain is passing cards in a very unlikely way.

The following hand is guarantee to shooting the moon for any hearts distribution besides the one that all the other 7 hearts are held by a single villain:

Hand: A2♣️, AKQ♠️, AKQJT932♥️, and you pass the 32♥️,2♣️ and get passed some XYZ

so post-pass the hand is: A♣️, AKQ♠️, AKQJT9♥️, XYZ

• Trick 1: some villain leads the 2♣️ and you grab the lead with A♣️.
• Trick 2-4: lead A♠️ then K♠️, and Q♠️ which break hearts.
• Trick 5-10 lead AKQJT9♥️ and hope that no one holds all the other 7 hearts.

This hand does not guarantee to shot the moon only if a single villain pre-passing held 87654♥️, did not pass any heart and got your passed 32♥️.

Two thoughts:

1. We are missing a single heart in order to guarantee the moon.
2. How likely a player holding 87654♥️ to pass some of his hearts?
