Description

I have checked that this issue has not already been reported.
-
I have confirmed this bug exists on the latest version of pandas.
-
I have confirmed this bug exists on the master branch of pandas.
Reproducible Example
import pandas as pd
from datetime import datetime
with pd.ExcelWriter("file.xlsx",engine="openpyxl",engine_kwarg={"iso_dates":True}) as writer:
pd.DataFrame([datetime(1996,20,10)]).to_excel(writer)Issue Description
the arguments are silently not passed through to the openpyxl Workbook class.
Expected Behavior
This should either raise or pass through to the engine
