GeoServer does not, indeed, support the LERC compression.
If you'd like to see support for this compression implemented, see
this guide:

Dear all,
I am serving a set of Geotiff raster files as single-file stores in
GeoServer and so far everything went fine with GeoTiff files
compressed
with the DEFLATE or ZSTD algorithms.
This week I have been testing LERC compression (with different values
for the gdal MAX_Z_ERROR option) and when serving those in
GeoServer any
WMS request results in a NullPointer Exception message instead of the
requested PNG tile.
Does GeoServer not read LERC-compressed files? Or is the cause
somewhere
else?
I can open the LERC-compressed GeoTiff files just fine in QQIS.
