I have heard that 10% tongue is ok here I have done 12% that is a difference of about 140lbs for tongue weight.
No
10% *MIGHT* be ok, but that is highly unlikely. For example, my trailer is far less stable with anything less than ~14% TW. Typical is between 12-15% for a TT.

You don't want to lighten the tongue to stay within your GVWR, it can lead to instability.
Something you can take into account is the fact that the WD hitch will transfer some of the tongue weight back onto the trailers axles. The amount can vary depending on set up but you could see as much as 20% transferred. At 20% of 900lbs you could see 180lbs removed from the truck. BUT, if you need to rely on this to stay within GVWR it goes to show that the TT is too much. Keep in mind your kids aren't going to get any smaller.
To expand on what is being said in the two quotes above...
Considering a 10% TW is absolutely wrong. As mentioned, this can lead to instability. The instability mentioned is a very uneasy, white knuckle experience which can also be referred to as trailer sway...TT not tracking behind the tow vehicle well. Many new RVers are told that this feeling is supposed to be what is helped out by a weight distribution hitch but very light TW problems will not be fixed by a WDH/Anti-sway...you will need to properly tongue load that trailer to get it to tow correctly. You will still need a WDH but don't be fooled into thinking a WDH will solve all TT tracking issues.
There are also cases where someone may already be at 13% TW but they still get an uneasy sway feeling...and usually, the quickest/easiest/proper way to resolve this is to continue to move heavier items forward of the trailer axles to increase the TW.
Trailer sway happens as the leverage of weight behind the trailer axles ease up on the hitch, allowing the TT to "have a mind of its own" causing the instability. This is a very general view of what is occurring but is essentially what happens.
You do not want this instability feeling while towing your family around.
