Can two briefs/ pads be used at the same time (also known as diaper doubling)?

No, doubling up on products that contain a moisture barrier will not increase absorption. Briefs, disposable underwear and pads/ liners are typically designed with a moisture proof backing that stops the urine from passing through. This approach to adding more capacity or addressing leakage concerns only works if the second product is a “flow-through” design with no moisture proof backing.
