OWNEREPOCH MSRs

Quoting the Intel SGX Programming Reference:
Owner Epoch is a 128 bit value which is loaded into the SGXOWNEREPOCH0 and SGXOWNEREPOCH1 MSRs when Intel SGX is booted. These registers provide a user with the ability to add personal entropy into the key derivation process.
What are the addresses of these MSRs? They are only referred to by names in the quoted document. Is it possible to change their values after the system boot? What about reading their values using the rdmsr instruction?
