Thankfully Marriott has a Help page that addresses your question directly:

How do I Gift a Reservation to family or friends using my Marriott Bonvoy® Points?

I suspect the really important FAQ is this one:

Will I or the Gift Reservation Recipient earn any Bonvoy® Points/Miles, Elite Night Credit, Qualifying Nights, or Qualifying Stays?

• No, with a Gifted Award Redemption Stay, neither the Member nor the Recipient will earn any Marriott Bonvoy® Points/Miles, Elite Night Credit, Qualifying Nights, or Qualifying Stays in connection with the Gifted Award Redemption Stay.

There will be many here that tell their anecdotes about how they did receive the points and stay credit in this type of scenario. As ever, YMMV in this respect. But it's there in black and white that you shouldn't so if for reasons you do then I'd keep quiet about it.
