I am running GDAL 3.4.1, released 2021/12/27
I don’t need the fill style as I can fill that with code, just need the geometry.
I added it though not really sure what value to use. Based on the current options I used --config DXF_HATCH_TOLERANCE value vs --config DXF_HATCH_TOLERANCE=value as the latter gives me an error. My full options are:
"-f GPKG --config DXF_ENCODING CP1252 --config DXF_HATCH_TOLERANCE 5 --config DXF_INCLUDE_RAW_CODE_VALUES TRUE --config DXF_TRANSLATE_ESCAPE_SEQUENCES FALSE --config DXF_MERGE_BLOCK_GEOMETRIES FALSE --config DXF_INLINE_BLOCKS TRUE -nlt geometry"
I tried values of 1, 5, 10, 50 and do not get anything. Maybe something else in my parameters are incorrect. I was not really sure what to use for some of the parameters, but found this parameter string on another forum and it worked for most of my needs other than the issue with the hatches not converting properly and missing symbology for the geometry.

What version of ogr2ogr are you using?
Look at the .dxf driver page:
Blockedhttps://gdal.org/drivers/vector/dxf.htmlBlocked
HATCH: Line and arc boundaries are collected as a polygon geometry, but no effort is currently made to represent the fill style of HATCH entities. Behavior is affected by the following configuration option:
DXF_HATCH_TOLERANCE=value: Determines the tolerance used when looking for the next component to add to the hatch boundary.
(GDAL <= 2.2.x) Only line and polyline boundary paths are translated correctly.
