Ignore invalid scopes while generating token - oauth-2.0

Question

We are in the process of upgrading our keycloak setup from 6.0.1 to 11.0.0 and it seems like from Keycloak 10 onward the token generation complains with error "invalid scope" if the scope parameter is invalid.
Intially we were using Keycloak 3 with RBAC (user and roles assigned to them) and full scoped clients (only Direct Access Grants Enabled = true) this used to worked fine where we were passing required roles in scope and used to get access token for request roles (in scope) and later we updated it to Keycloak 6 which used to work fine with this setup as well, however updating it to Keycloak 11 breaks it since we do not use fine grained scopes so passing existing roles to scope sort of broke it, however if I do not provide any scope then it works fine.
My setup looks like below
Roles:
Role1
Role2
Role3
Users:
User1
User2
User-Role Mapping
Role1, Role2 --> User1
ROle3 --> User2
Clients
Client1
AccessType: Cofidential
Direct Access Grants: Enabled
Scoped: Full Scoped
