Logic Gap

Removing the enum validation check could potentially allow invalid enum values to be processed, which might cause runtime issues if the enum is cast from an integer or manipulated unsafely elsewhere in the codebase.

best practice
Use string interpolation instead

Replace the verbose string.Format call with string interpolation for better
readability. The CultureInfo.InvariantCulture can be maintained using the
interpolation format specifier.

dotnet/src/webdriver/Chromium/ChromiumDriverService.cs [163]

-argsBuilder.Append(string.Format(CultureInfo.InvariantCulture, " --log-level={0}", this.LogLevel.ToString().ToUpperInvariant()));
+argsBuilder.Append($" --log-level={this.LogLevel.ToString().ToUpperInvariant()}");

Why:
Relevant best practice - Use proper string interpolation instead of verbose string.Format calls for cleaner and more readable code

Low
General
Add defensive enum handling

While removing the enum validation is reasonable for compile-time safety,
consider that enums can still have invalid values at runtime through casting or
serialization. Add a defensive check or use a switch expression to handle only
known enum values explicitly.

dotnet/src/webdriver/Chromium/ChromiumDriverService.cs [161-164]

 if (this.LogLevel != ChromiumDriverLogLevel.Default)
 {
-    argsBuilder.Append(string.Format(CultureInfo.InvariantCulture, " --log-level={0}", this.LogLevel.ToString().ToUpperInvariant()));
+    var logLevelString = this.LogLevel switch
+    {
+        ChromiumDriverLogLevel.Info => "INFO",
+        ChromiumDriverLogLevel.Warning => "WARNING", 
+        ChromiumDriverLogLevel.Severe => "SEVERE",
+        _ => this.LogLevel.ToString().ToUpperInvariant()
+    };
+    argsBuilder.Append(string.Format(CultureInfo.InvariantCulture, " --log-level={0}", logLevelString));
 }

Suggestion importance[1-10]: 5

__

Why: The suggestion correctly identifies that removing the Enum.IsDefined check could allow invalid enum values at runtime, but the proposed switch expression with a default fallback case does not fix this potential issue and behaves identically to the PR's code for unknown values.
