Unable to process password variable in powershell because of special characters

Hi Team, I am working on a PS script to install VSTS agents on my Azure VMs through an Azure DevOps Release Pipeline.

Here in the below script, I am passing a Service Account Password, which is set by my customers. Below script fails whenever Password consist of special characters like

")';:( 

 .\config.cmd --deploymentgroup --deploymentgroupname DeployGroupSQL --agent $env:COMPUTERNAME 
--runasservice 
--windowsLogonAccount $(ServiceAccountUser) 
--windowsLogonPassword "$(Service_Account_Password)" --work '_work' 
--adddeploymentgrouptags --deploymentgrouptags $SQL 
--url 'https://dev.azure.com/campusmgmt-product-development/' 
--projectname 'Student' --auth PAT --token u4bq6j******************************bhhyq; 

I have tried putting whole password into double quotes as well as single quotes but of no help.

This Service Account Password is a Pipeline variable and hence needs to be passed like $(Service_Account_Password).

Can you please suggest on how can I deal with this situation. I have already tried putting this as a here-string, Secure-String, or script parameter but has not proved of any help.

Hoping to hear back soon as this is urgent for my project release.
