Very possible. You just use dbutils.widgets.get().

For instance I set up a job with the following param:

{
  "foo": "bar"
}

 The primary notebook:

the_arg = dbutils.widgets.get("foo")
 
print(the_arg)
 
nb1 = dbutils.notebook.run('./notebooks_sec_1', 0, {"foo" : the_arg})

notebooks_sec_1:

the_arg = dbutils.widgets.get("foo")
 
print(the_arg)

Then, when I ran it, both printed: "bar".
