[FFmpeg-user] How to set FLAC --no-padding equivalent switch in FFMPEG?

[Барт Гопник]

This is how I use FLAC:
flac --best --no-padding input.wav

Is there equivalent to FLAC's --no-padding switch/parameter/option (
https://xiph.org/flac/documentation_tools_flac.html#negative_options) in
FFMPEG?

BTW, what is equivalent value of -compression_level switch in FFMPEG to
--best (
https://xiph.org/flac/documentation_tools_flac.html#flac_options_best)
switch in FLAC?
(In FLAC --best currently synonymous with -8, or --compression-level-8, or
-l 12 -b 4096 -m -e -r 6)

What is maximum value of -compression_level switch for FLAC codec in FFMPEG?
