GDA2020 support

[Eskapp]

This stems from an issue that I currently have: I want to convert a pair of latitude/longitude in UTM in the GDA2020 datum.
From my experiments I am thinking that this is not supported. Maybe it is just the fact that I don't use the library properly so let me explain the way I have been trying to realize this tramsformation:

Let's say thatI want to convert the (latitude, longitude) pair: (-27.45745, 153.05715) to UTM in the GDA2020 datum. The UTM zone is 56J.

from pyproj import Proj
proj_utm = Proj('proj=utm +zone=16J, +south +ellps=GRS80 +datum=GDA2020 +units=m +no_defs')

returns the following error:

pyproj.exceptions.CRSError: Invalid projection: +proj=utm +zone=56J, +south +ellps=GRS80 +datum=GDA2020 +units=m +no_defs +type=crs: (Internal Proj Error: proj_create: Error -9 (unknown elliptical parameter name))

The error message is a bit inaccurate as the ellipsoid GRS80 is actually known if I use the datum NAD83 (for North American pairs of latitude/longitude).

Is the GDA2020 datum defined in Pyproj? If not, is there a way to do this conversion using the library?
I stumbled across posts to convert from GDA94 to GDA2020 but I am struggling to get the GDA1994 to work in pyproj.

Thanks!

from pyproj.crs import GeographicCRS, ProjectedCRS
from pyproj.crs.coordinate_operation import UTMConversion

proj_crs = ProjectedCRS(
    conversion=UTMConversion("16", "S"), geodetic_crs=GeographicCRS(datum="GDA2020")
)

This produces:
