How Can I Exclude Specific Records Correctly - SQL Server

I have a table with Clients and their labels (saved in a single column separated by comma).
I need to find a way to EXCLUDE clients with SDRC label.

CREATE TABLE FakeData
(
    ClientId INT, 
    ClientLabels VARCHAR(MAX)
);

INSERT INTO FakeData
VALUES (1, 'ABA, SDRC, California'),
       (2, 'SLP, Texas, SDRC (0-3)'),
       (3, 'ABA, SDRC (0-3), SDRC, Virginia'),
       (4, 'OT'),
       (5, 'ABA, SDRC (6+)'),
       (6, 'SLP, SDRC, Texas, SDRC (12+)')

SELECT * FROM FakeData

The output I need:

I was thinking of using STRING_SPLIT, however it did not work.

SELECT * 
FROM FakeData
WHERE 'SDRC' NOT IN (SELECT VALUE 
                     FROM STRING_SPLIT(FakeData.ClientLabels, ','))

And obviously below code will not work as well.

SELECT * 
FROM FakeData
WHERE FakeData.ClientLabels NOT LIKE '%SDRC%'

How about this:

SELECT * 
FROM FakeData
WHERE 'SDRC' NOT IN (SELECT TRIM(VALUE) FROM STRING_SPLIT(FakeData.ClientLabels, ','))

You can use STRING_SPLIT as a table:

SELECT ClientId, ClientLabels
  FROM @FakeData
    CROSS APPLY STRING_SPLIT(ClientLabels, ',') s
 GROUP BY ClientId, ClientLabels
 HAVING MAX(CASE WHEN TRIM(value) = 'SDRC' THEN 1 ELSE 0 END) = 0

Re-aggregating it after making your comparisons. To alter the filter just add or remove values in the case statement.

The simplest way if you must store data like this, would be to use a like match

select * 
from FakeData
where Concat(', ', ClientLabels, ', ') not like '%, SDRC, %';
