Are you thinking then to unregister the tpm hwrng "sometime" after boot?
No, I was more thinking that instead of registering it as a randomness source, you'd just do a one-time
tpm_get_random(..); add_hwgenerator_randomness(..);
and leave it at that.
Even if there is some stutter due to some crazy firmware implementation for reading the random data, at boot time nobody will notice it.
