Conditionally Filter Specific Visuals Based on Current User Logged In

You can do this with a calculation group and a measure to use as a filter.

First you need to modify your measure

02 Should Current User Be Filtered = 
VAR CSRFilterEmailList = 
    //ONLY NON-MANAGER CSR'S SHOULD HAVE DATA FILTERED
    CALCULATETABLE(
        ALL('Dim CSR'[Email]),
        'Dim CSR'[IsManager] = 0
    )
VAR CurrentUser = [01 Current User]
VAR ShouldCurrentUserBeFiltered =
    //VERIFY IF CURRENT USER LOGGED IN IS A NON-MANAGING CSR.
        //IF YES THEN WE NEED TO FILTER CSR SLICER & CSR TABLE VISUALS BY CURRENT USER LOGGED IN
        //IF NO THEN DO NOTHING.  I.E. DO NOT FILTER THESE VISUALS BY THE CURRENT USER LOGGED IN
    IF(
        CONTAINS(CSRFilterEmailList, 'Dim CSR'[Email], CurrentUser),
        1,
        0
    )
RETURN ShouldCurrentUserBeFiltered

Rather than using VALUES it uses ALL to remove the filters placed by the visuals.

Create a calculation group with a calcultion item

Apply Filter = IF( [02 Should Current User Be Filtered],
    CALCULATE(
        SELECTEDMEASURE(),
        KEEPFILTERS( TREATAS( { [01 Current User] }, 'Dim CSR'[Email] ) )
    ),
    SELECTEDMEASURE()
)

Apply this as a filter to the table visual. It will only show the relevant CSRs.

Create a new measure

Is CSR Visible = IF (
    [02 Should Current User Be Filtered],
    VAR VisibleEntries =
        CALCULATETABLE (
            VALUES ( 'Dim CSR'[Name] ),
            TREATAS ( { [01 Current User] }, 'Dim CSR'[Email] )
        )
    VAR Result =
        IF ( SELECTEDVALUE ( 'Dim CSR'[Name] ) IN VisibleEntries, 1, 0 )
    RETURN
        Result,
    1
)

Add this as a filter to the slicer, to only show when the value is 1.
