You can create interface endpoints with the CDK

Here is the method on the VPC Construct

https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-ec2.Vpc.html#addwbrinterfacewbrendpointid-options

Here is an example of creating a RDS endpoint in Python

vpc.add_interface_endpoint(
            'VPCRDSInterfaceEndpoint',
            service=ec2.InterfaceVpcEndpointAwsService('rds'), 
            private_dns_enabled=True,
            subnets=ec2.SubnetSelection(
                one_per_az=False,
                subnet_type=ec2.SubnetType.ISOLATED
            ),
)
