The judge explicitly said, yes, they can (page 179):
The relief to which Apple is entitled is that to which Epic Games stipulated in the event that the Court found it liable for breach of contract, namely:
(1) damages in an amount equal to (i) 30% of the $12,167,719 in revenue Epic Games collected from users in the Fortnite app on iOS through Epic Direct Payment between August and October 2020, plus (ii) 30% of any such revenue Epic Games collected from November 1, 2020 through the date of judgment; and
(2) a declaration that (i) Apple’s termination of the DPLA and the related agreements between Epic Games and Apple was valid, lawful, and enforceable, and (ii) Apple has the contractual right to terminate its DPLA with any or all of Epic Games’ wholly owned subsidiaries, affiliates, and/or other entities under Epic Games’ control at any time and at Apple's sole discretion.
This may very well kill Epic's Unreal Engine business (at least on Apple platforms) if they no longer have the necessary licenses to use Apple's developer tools.
