SQL to filter the data from inner query based on 2 conditions

I have the following table named TableB:

I have another table named TableA:

I would like to exclude the data present in TableA based on Partid AND Datetime in TableB.

I want the list of CustomerID from TableA based on ONLY those Part-A & Part-B Partid's which ONLY fall between DateTime 2022-12-24T15:20:00.782Z and 2022-12-22T15:22:00.782Z in TableB.

The desired output is:

WITH TableCTE AS (
SELECT DISTINCT a.*,b.Partid as 'BId'
FROM #TableA a
LEFT JOIN #TableB b ON a.Partid = b.Partid AND a.Datetime=b.Datetime
)

Select * from TableCTE where Bid is NULL
