I'm using WSO2 Identity Server (IS500) with my own SAML2 service provider implementation. Don't want the 'resident service provider' provided by WSO2 Identity Server to be accessible or support any logins. Can I disable a feature to remove this?
There is no any inbound authentication configuration is defined for Resident Service Provider by default. Therefore, it can not be used to authenticate using SAML2/OAuth2/OpenId or any other way. You can not completely remove the Resident Service Provider using management console. but you can find configuration of from the SP_APP table in identity database. Basically it is totally fine to keep it.
