No. Sell that bike as is and replace it with a small. Your dealer should be ashamed of themselves for selling you a size large at 5’4”
That same exact bike but in the right frame size for you would feel worlds better
The tires on the bike are already 2.4 inch with Changing to 2.5 would not be life-changing. However if you were riding off-road conversion to tubeless does have benefits but would need tubeless compatible tires
But it’s a moot point since the bike is two sizes too large for you
