Wiegman admitted before kick-off it had been a "hard" start to the week following Earps' announcement, which led to criticism over the Paris St-Germain keeper's timing and whether the squad would be affected.
The manager fielded questions on the pressure it could put on Hampton and other members in the squad who would be forced to step up in the absence of Earps' experience and leadership.
But the goalkeeping position was not the story at full-time as England's creators enjoyed themselves and showed their attacking quality.
Beever-Jones, who scored nine goals in 22 appearances for Chelsea this season, has grown immensely in the past year and thrived on the main stage.
The 21-year-old looked at home from the first minute, hassling Portugal's weary defence and linking up well with Manchester City's Jess Park and Arsenal forward Mead.
She was deserving of her hat-trick and also played a role in Bronze's header, flicking on Hemp's cross to tee up the Chelsea defender to nod the ball home from a few yards.
Beever-Jones joins Mead as the only female players to score a hat-trick for England at Wembley.
The job was done at half-time but England took their opportunity to build momentum, pinging the ball around from back to front and linking up nicely in attack.
It was a completely different performance to the disjointed ones they produced in a 3-2 defeat by Belgium last month, and the away fixture in Portugal which ended in a 1-1 draw in February.
When the heat was on, when the noise was dialled up, the Lionesses rose to the challenge and that will give them huge confidence as they prepare to travel to Switzerland for their Euro 2025 opener on 5 July.
"This game was really important because we knew if we won then we would be in a good position for the World Cup draw and at the same time we're preparing for the Euros," said Wiegman.
"We wanted to secure second spot in the Nations League and now we move on and go to Spain [on Tuesday] and that is what the focus is on right now."
