You can now setting "go.formatTool": "golines" and it will work together with gopls. Closing.

but when I set this configuration option go.formatTool": "golines, I get the error message: Value is not accepted. Valid values: "default", "gofmt", "goimports", "goformat", "gofumpt", "custom".

    "go.formatTool": "custom",
    "go.alternateTools": {
        "customFormatter": "golines" <--- or exact path like "~/go/bin/golines". 
    }
}
