Your only option is to book an appointment with one of the Service Canada location that offers biometric services whenever they resume operation. You can’t give biometrics at a police station, you have to take that trip no matter how far from your location it is.
About biometrics slowing down your application, you aren’t the only one, a lot of people in this forum are facing the same issue. I applied since mid March and the only thing delaying my app from getting approved is biometrics. IRCC will keep processing your application without biometrics. So take a seat, relax and enjoy the long ride.
