Dubois has taken aim at Baumgardner and called her out for a high-profile clash, saying the clash "has to happen sooner rather than later".
"She's lost right now," said Dubois. "She's got no opponents. She wanted the Katie Taylor fight but that's not happening, she wanted the Amanda Serrano fight but that's not happening, so who's she going to fight? Absolutely nobody.
"There's no one she can step into the ring with that's on my level. I say that with respect but I know I'm her biggest challenger.
"We're going to build the fight. I want to become undisputed and then she's got no arguments. All we can do is to build and make that fight unavoidable, unmissable, and undeniable. That happens by me becoming undisputed."
A 10-round junior middleweight championship unification fight between Mikaela Mayer and Chantelle Cameron will headline a main card in Birmingham and Dubois said: "It's a close fight - I'm split. Mikaela Mayer has got a bit more dimensions but then I wake up and think Chantelle Cameron is a beast. She's going to bring the pressure and she has the home advantage.
"It's a 50-50 fight. I know it's going to be a great fight."
Trainer Shane McGuigan hinted at MVP's interest in a blockbuster showdown with Irish boxing icon Katie Taylor, who is set to end her stellar career with a fight against unbeaten French fighter .
"Katie Taylor is the GOAT," Dubois said. "She's a champion and she deserves to fight whoever she wants to fight. She sold out 80,000 which is phenomenal. It doesn't matter who is in the corner. This is about Katie Taylor. It's not about the fight!
"She's getting the moment to sail off into the sunset exactly the way she wants to. I'll be supporting her. No one can discredit who she's fought and who she has been in the ring with and her tenacity throughout the years.
"I would 100 per cent be backing myself [if I had the chance to fight her] and it would have been an awesome fight to have. I would have loved to have fought her straight out of the 2012 Olympics.
"It's not going to happen and I'm not focussing on that. If there were no other women to fight then I would be upset, but I've got big names."
