I am looking at

(A): https://proj4.org/operations/projections/aeqd.html#cmdoption-arg-ellps

and

(B): http://epsg.io/54032 Description: +proj=aeqd +lat_0=0 +lon_0=0 +x_0=0 +y_0=0 +ellps=WGS84 +datum=WGS84 +units=m no_defs

wondering if they are the same thing.

If they are, does the argument +ellps=<value> in (A) correspond to +datum= in (B)?

Also, what does no_defs mean? I didn't find a simple explanation.
