Not currently. The closest you can get currently is using -cpu max which
will bring in all the ARMv8.x features currently implemented in QEMU. It
there any particular architectural feature you are interested in or is
it the complete model that is of interest?

We hope to implement a Cortex-A76 model in the next development cycle
(hopefully for QEMU 6.1). The biggest chunk of work is implementing the
GICv4 and GIC ITS emulation. From there on the aim is to add models for
Neoverse N1/V1 in future releases.

If you want to help with test and review I can ask the various authors
to Cc you on patch sets.
