There's a sequence of thirteen eights, and twelve of each of the other digits, documented at [0] which covers the first 2.7 trillion digits. Based on that you can be all but certain any given ten-digit sequence, including 0123456789, has also been found.

I dunno about "known" but you can get a billion digits pretty easy.

  $ wget https://stuff.mit.edu/afs/sipb/contrib/pi/pi-billion.txt
  $ grep -ob 012345678 pi-billion.txt
  956753746:012345678
  $ grep -ob 0123456789 pi-billion.txt
  $ 

So close, and amusingly close to the end of the file!

Using this website:

I can search for the sequence 0123456789. It is not found in the first 200M digits.

Lo! Technology: https://www.angio.net/pi/

It surely does appear somewhere. But it isn't within the first 2 billion digits.
