Description
There are wider instructions on aarch64 just like VAES on x86-64. GitHub Actions runners like ubuntu-24.04-arm support them, which should help with testing:
Architecture: aarch64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3
Vendor ID: ARM
Model name: Neoverse-N2
Model: 0
Thread(s) per core: 1
Core(s) per socket: 4
Socket(s): 1
Stepping: r0p0
BogoMIPS: 2000.00

Rust standard library doesn't have intrinsics for it though (yet):

Research direction
Start by reviewing the linked Rust standard-library and stdarch issues to determine whether SVE AES intrinsics are available. Then identify the architecture-specific AES implementation and existing GitHub Actions tests in this repository; done means SVE AES support is integrated and verified on an ubuntu-24.04-arm runner.
