I agree with mattmc82.
The CARES Act does not impact if/how many loans are allowed by the plan document. If the plan does not allow loans, it could choose to allow them at this time, or not. If a plan only allows three loans (or one loan), the CARES Act doesn't change that. A Plan Sponsor could certainly choose to amend the number of loans allowed at one time, but the CARES Act does not do this automatically.
