Yes there is no separate Lookahead bitrate mode but you can enable/change Lookahead for AV1 with the use of --la-depth in CBR/VBR bitrate mode.

You can use this setting also in combination with --scenario-info game_streaming which works differently there. Try --la-depth 4 and --la-depth 50 and you see what I mean.
