Dock is not disappearing with HomeScreenLayout payload

We are pushing a HomeScreenlayout payload with no "docks" array .

The behaviour in iOS's is the dock at the bottom is disappeared. But in ipadOS's , dock is still at the bottom with recent apps listed there. Attached is Screenshot for the ipad's behaviour .

Payload :

			<integer>1</integer>
			<key>PayloadUUID</key>
			<string>____________-</string>
			<key>PayloadType</key>
			<string>com.apple.homescreenlayout</string>
			<key>PayloadOrganization</key>
			<string>MDM</string>
			<key>PayloadIdentifier</key>
			<string>_______________</string>
			<key>PayloadDisplayName</key>
			<string>Homescreen Layout</string>
			<key>Pages</key>
			<array>
				<array>
					<dict>
						<key>BundleID</key>
						<string>com.apple.mobilephone</string>
						<key>Type</key>
						<string>Application</string>
					</dict>
					<dict>
						<key>BundleID</key>
						<string>com.apple.Preferences</string>
						<key>Type</key>
						<string>Application</string>
					</dict>
					<dict>
						<key>BundleID</key>
						<string>com.google.ios.youtube</string>
						<key>Type</key>
						<string>Application</string>
					</dict>
					<dict>
						<key>BundleID</key>
						<string>com.manageengine.mdm.iosagent</string>
						<key>Type</key>
						<string>Application</string>
					</dict>
				</array>
			</array>

Is it possible remove the dock from iPadOS or is there anything am i missing to disable the dock or distinguish between dock added apps and Recent Apps?
