SARIMAX: Calculating the Seasional_order(P, D Q, M) values

Is there a function or library (like auto_arima to get the order(p,d,q) values) available to calculate the P, D, Q and M values to be used in Seasional_order(P,D,Q,M) in SARIMAX model. Thanks,

Can anyone explain the number for each parameter in SARIMA?

I used auto_arima function with seasonality to forecast covid19 and got ARIMA(0,1,1)(2,0,2) Can anyone explain me the reason for each parameter (p,d,q)(P,D,Q)? (Ex: why AR is 0 meanwhile SAR is 2)
