how to add select statement in IN clause in pivot

iam using pivot table in SQL query.. i need to make some columns as rowss, but i need to use select statement in IN clause where we givt option like this

    PIVOT(
   sum(target)
    FOR collectionName IN (
 Select Ds.CollectionName as 'CollectionName'

from v_DeploymentSummary Ds

left join v_CIAssignment Vaa on Ds.AssignmentID = Vaa.AssignmentID

left join v_AuthListInfo LI on LI.ModelID = Ds.ModelID

Where Ds.FeatureType = 5 and Ds.CollectionName  not like '%Windows 8%'

and Li.Title like '%SUG_2020_06_P0_W7-W8-1_Critical%'
)) AS pivot_table

normally we give option like

    ) t
PIVOT(
   sum(target)
    FOR collectionName IN (
        [W7-8.1 - Ring 2 - Laptops Wave 5],
[W7-8.1 - Ring 2 - Laptops Wave 4],
[W7-8.1 - Ring 2 - Laptops Wave 3],
[W7-8.1 - Ring 2 - TARA -BI],
[W7-8.1 - Ring 2 - Desktops],
[W7-8.1 - Ring 2 - Laptops Wave 2],
[W7-8.1 - Ring 2 - Laptops Wave 1],
[W7 - Ring 1 - Early adopters],
[W7 - Ring 0 - Fast ring]
)) AS pivot_table
