Is it possible to use the TRNG in the security enclave directly in M1?

So in the past I've used RDRAND in Intel to directly access the true random number generator but now I'm thinking of rewriting my app for M1 - is there some similar intrinsic to _rdseed16_step?

Or is the only as stated here by the kernel using getentropy or /dev/random - I don't want to mix with other entropy sources but directly access the security enclave TRNG.
