4 official rulings from Bandai, last ruled Sep 13, 2024. Straight answers to how this card actually resolves.

Does "you may play 1 of each Digimon with the [Royal Knight] and a different name from the digivolution cards of Digimon in the breeding area without paying the costs" in this card's <On Play><When Digivolving> effect mean that I can play a Digimon card with the [Royal Knight] without the name [Omnimon]?
No, this effect plays 1 of each Digimon with the [Royal Knight] and different names from among the digivolution cards. For example, if the target digivolution cards are [Omnimon], [Alphamon], [Alphamon], [Gallantmon], and [Gallantmon (X Antibody)], you would leave 1 [Alphamon] since it has the same name, then play[Omnimon], [Alphamon], [Gallantmon], and [Gallantmon (X Antibody)]. Note that the [Omnimon] where this effect activated isn't a digivolution card, therefore you can use this effect to play 1 [Omnimon] from among the target cards.

When I use this card's <On Play><When Digivolving> effect to play Digimon, can I choose just the cards I want to play from among the cards I can play?
No, you can't. You must play all of the Digimon that you can play or play no Digimon.

This card's <On Play><When Digivolving> effect reads "trash your Digimon in the breeding area" for when a Digimon is played by this effect, but what happens to the remaining digivolution cards under this Digimon?
The digivolution cards are also trashed.

I used this card's <On Play> effect to trash a BT13-007 [King Drasil_7D6] with a BT17-078 [Omnimon ACE] in its digivolution cards. Is BT17-078 [Omnimon ACE]'s <Overflow> processed at such times?
Yes, it's processed. <Overflow> is processed when a card is sent from the area or from under a card to another area. In this case, <Overflow> is processed because a card is placed in the trash from under another card.
