i assume its measured under laboratory conditions, so it seems ok to me. TCXO, OCXO should usually be operated within their operating voltage range. depends on type. usually i would assume 1.8-3.3v, but who knows without datasheet?

it could be worth a try to contact diodes and ask which components use or have used in the past V-QFN2030-12 (Type HE) package
diodes uses packages like this one: https://www.diodes.com/assets/Package-Files/V-QFN2030-12-Type-HE.pdf but cant find FMM marking there ...
unfortunately i neither could find anything. richtek has some weird packages like this:
or like this:
so i poked around their homepage. but could not find anything with that pinning. also FMM marking is not in their marking reference :(
How many pins does it have? I can't see it properly in the image. Is it 4, 8 or 12 pins?
https://sensepeek.com/ do manufactur those nice PCBite SP10 probes. New improved series: SQ10 probes. They also have 500MHz Oscilloscope probes! They are awesome :D
Then there are those small pincers: https://at.rs-online.com/web/p/klemmprufspitzen/0775704 Or very small pincers: https://www.sks-kontakt.de/de/test-measurement/produkte/produkt?nr=9741011 (digikey lists them as manufacturer Altech Corporation)

i would probably do some circuit with a TL431 and FETs, but this also drains some small amount of battery current.
