You can ask both of your providers to use manipulated weight to set the route preference on the ASBR's connecting to your network.
MED, Multi Exit Descriminator can be used.
Can you explain your scenario more clearly using ip format if possible with two ISP's connectivity.
Thanks and Regards

ask your provider1 NOT to aggregate your /23 block, instead advertise it
alone, AND put more AS # in your updates to provider2 so as to make the
route(AS_path) longer for them to reach you.
