How to get week start date from time stamp in SQL

I have a data source with a bunch of time stamps. I want to find the week start (sunday) date from these time stamps.

Eg, I want to go from "2022-11-23 00:00:00.0" –> "2022-11-20" for every date in the column called "Received Date"

SELECT
    CASE
        WHEN sorttype = 'sortable' THEN 'Sort'
        WHEN sorttype = 'SORTABLE' THEN 'Sort'
        ELSE 'Non Sort'
    END AS "Sort Type",
    DATEADD(week, DATEDIFF(week, -1, (order_day + podays_received)), -1) AS "Week Start",
    (order_day + podays_received) AS "Received Date",
    pg_rollup AS "Product Family",
    gl,
    quantity_unpacked AS "Quantity Received"
FROM 
    sba.sba_req_po_received
WHERE
    source = 'OPPORTUNITYBUYING'
    AND country_code = 'US'
    AND NOT buy_type_name = 'Offcycle'
LIMIT 100;
