How to use union statement on entity framework core instead of using s

I work on entity framework core 7 . I face issue I can't do or use union on entity framework core instead of use union on sql server

so i have view contain or return collect of unions as below

CREATE VIEW [dbo].[vDsales]
AS
SELECT        sldate, id, sdate, till, cashier, trnno, brcode, itemno, qty, price, amt, itemflag, stime
FROM            NewSaleNAV.dbo.dsales WITH (NOLOCK)
WHERE        sldate >= '2023-01-01'

UNION
SELECT        sldate, id, sdate, till, cashier, trnno, brcode, itemno, qty, price, amt, itemflag
FROM            NewSaleNAV01.dbo.dsales WITH (NOLOCK)
WHERE        sldate >= '2023-01-01'

UNION
SELECT        sldate, id, sdate, till, cashier, trnno, brcode, itemno, qty
FROM            NewSaleNAV_Arc22.dbo.dsales WITH (NOLOCK)
WHERE        sldate >= '2022-01-01'

UNION
SELECT        sldate, id, sdate, till, cashier, trnno, brcode, itemno, qty
FROM            NewSaleNAV01_Arc22.dbo.dsales WITH (NOLOCK)
