Not the parameters you showed, they are queue-manager parameters, not
SMTP client parameters.

The parameters that are relevant to smtp(8) are specified in the smtp(8)
manpage:
http://www.postfix.org/smtp.8.html

No, tuning queue-manager parameters is not possible through "-o"
overrides in the master.cf entry for smtp(8).

Indeed this is not correct. These are queue-manager parameters.

These overrides have no effect on smtp(8). And you are trying to change
parameters you really should not be changing.
If you can't explain how the "default_delivery_slot_<mumble>" variables
achieve your goals, you should not (attempt to) modify these parameters.
