No. afl requires an instrumented (compiled with extra information) executable, and watches the code paths. When fuzzing a seed finds a new code path, it will recycle that fuzzed version as a new seed.

ASLR can help prevent successful exploitation of bugs that afl might find, but it won't prevent the program from crashing in the first place.

(Plus, since afl requires compiling the binary, I doubt it bothers to enable ASLR. There's no benefit for fuzzing purposes.)

Can you fuzz an uninstrumented executable to add instrumentation?

You can add instrumentation to binaries using DynamoRIO or pin. This isn't currently supported by afl-fuzz out of the box, although there's nothing that makes it fundamentally difficult.
