SQL Not Like ^ Character

Question

Hello All,
Can you please help me with a SQL Transaction TSQL query.
The rules are these
- the query is a hard coded "LIKE" statement - I dont not have the ability to pass the word NOT.
- I wish to return all records where the first two characters of a field are not PA
Lets say the field "WORD" contains the following...
CARPET
PARTNER
PORTION
SALTS
PARAMETER
FAULT
I want to return all rows where the first two characters are NOT PA. (So exclude Partner and Parameter)
As the application passes everything in the query as a LIKE - I can only use the ^ parameter.
The where clause is hardcoded something along the lines "WHERE WORD LIKE @PARAMETER"
I have tried using a number of variable but cannot work out how to use the ^ character without eliminating records I actually want retrieved.
If I pass '%[^P]_________'  - It removes the rows I want but also removes PORTION which I actually want
If I pass %[^P][^A]_________' It removes all rows and returns nothing
Can someone please aide me with what may pass and only exclude words that start with PA.
Many Thanks

Try something below(you can have your own search conditions)
DECLARE @Sample TABLE(string VARCHAR(100));
INSERT INTO @Sample
values('CARPET'),('PARTNER'),('PORTION'),('SALTS'),('PARAMETER'),('FAULT')
Select string From @Sample where
string LIKE '%[^P][^A]'
Select string From @Sample where
string LIKE '[^P]%'
EDIT: Try the below:
DECLARE @Sample TABLE(string VARCHAR(100));
INSERT INTO @Sample
values('CARPET'),('PARTNER'),('PORTION'),('SALTS'),('PARAMETER'),('FAULT')
Select string From @Sample
where PATINDEX('[^PA]%',string) = 1 or charindex('PA',string)=0
