Not really. Most of commerical aviation doesn't use leaded fuel anymore, and general aviation uses leaded gasoline because it is technologically still mostly stuck in the sixties.

Most commercial aviation doesn't use leaded fuel because it uses Jet-A1 instead of AVGAS 100LL.

Replacements for currently used anti-knocking agents are searched for, but less so specifically because most commercial use involves Jet-A1, and low-end general aviation uses MOGAS where possible due to general lower prices (though those tend to vary - sometimes AVGAS 100LL can be wildly cheaper than MOGAS)
