When redirecting user from application to Okta for authentication is it possible to send user ID to Okta through OIDC request that way user ID is pre-populated for user to login?
In Our case application instance is Salesforce if that helps.

Yes, if you have access to custom authorization servers you will be able to add a custom claim to the token. See these instructions.
