TPS2660: Is it possible to change via size from 0.2 to 0.3 or larger?

Part Number: TPS2660

Dear Specialists,

My customer is considering TPS26602 and has a question about via size.

I would be grateful if you could advise.?

---

Datasheet P.49 EXAMPLE BOARD LAYOUT describes that Φ0.2 vias should be installed.

Are these necessary?
I would like to use vias with a diameter of 0.3 Φ or larger, is it possible?

Are there any points to keep in mind when enlarging the vias?

I appreciate your great help in advance.

Best regards,

Shinichi
