How can I set temperature for DeepSeek in VS Code AI coding extensions?

I’m using DeepSeek in VS Code, currently through the Vizards “DeepSeek V4 for Copilot Chat” extension with GitHub Copilot Chat. I’m trying to set temperature: 0.0 for coding/agent tasks, but I can’t find a temperature setting. I also checked Cline and don’t see a temperature option there either. Is there any VS Code extension or setup that actually lets me control DeepSeek API parameters like temperature for coding agents? Or is this currently only possible by patching/forking an extension or using somethin
