The Invocations from Tasha's Guide were under the umbrella of an Optional Feature. So theoretically, all of those could be considered as out of bounds for the 2024 Warlock since D&D Beyond does not currently support any Tasha's Optional features for the 2024 classes.
But the Invocations from Xanathar's Guide are NOT presented as optional features. They are simply additional options for Warlocks. They should certainly be available for characters build with expanded rules.
And of course, if and when optional rules are enabled for 2024, the Tasha's options should appear as well.
All features added to the classes from any book were added to the 2014 classes. 2014 and 2024 classes are different entities and don't share features directly in that manner.

Is there anyway to add invocations in through the homebrew options?
Unfortunately, there's no support for that currently. The best you can do is implement it as a homebrew feat.
