I think not. Because in "direct addressing" the value being
loaded is part of the command. "register addressing" would
load the value from another register. "indirect addressing"
loads the value from memory. There are other modes, such
as the referenced memory location containing a pointer to
a second location that contains the value you want to load,
and several methods of offsetting (indexed) from a point
in memory. It all gets very confusing to me.

But all of the methods become essential at one point or
another.
