They did all of that on screen, so abundantly yes. It's called a Reset Charge.The TVA managing to blindside the Asgardians within their own home?!
We're talking about the people who were responsible for sealing away the reality stone and you think someone time travelling would be able to bypass defences that would only eventually fail after Odin was incapacitated or dead?
Did they wipe the entire universe they acquired Sylvie from because that's the only way to avoid being discovered!
Completely mind wipe everyone on Asgard that knows about her is basically what that would have to achieve if its just pruning a branch.
So does that charge also erase any evidence of their presence and use of their tech in that location?
Sorry, but bloody hell the ramifications of this are far more serious than you might realise!
Okay, picture this. Child!Slyvie is playing. A nexus event/timeline split occurs because Child!Sylvie does something off the Sacred Timeline. Mind you, she's "normally" does what agrees with the Sacred Timeline. Poof, we have a Variant. This does not invalidate Non-Variant!Child!Sylvie - she shows up just fine. TVA shows up a few seconds/minutes later, takes Variant!Child!Sylvie and errases back to the point of split. All we have left is non-variant!child!Slyvie playing,a nd not the slightestr hint there was ever the TVA there because the entire (tiny) timeline that happened on has been reset.
