Lowpass filter adjustment?

As with most other lossy codecs, this is possible. How do I do this with Opus, if the switch exists at all?
I experiment a lot with this codec and would like to test its capabilities in this area very much.
Thank you.

In Opus, it makes no sense to have the same kind of lowpass filters as used in MP3 and Vorbis. However, at really low rates, you might want to simply set the "bandwidth" parameter that can be narrowband (4 kHz lowpass), wideband (8 kHz lowpass) or superwideband (12 kHz). In most cases, the default will be fullband (20 kHz).
