Locking InnerBlocks Template

I am trying to create a parent-child block in ACF by using InnerBlocks. The behavior I want is to lock the parent with some templates in the inner blocks like:

$template = [
	[
		"acf/acfb-my-child-block",
		[]
	],
	[
		"acf/acfb-my-child-block",
		[]
	]
];

<InnerBlocks templateLock="all" template="<?php echo esc_attr( wp_json_encode( $template ) ) ?>" />

Now user can insert more blocks from the child block like:

	$template = [
		[
			'core/paragraph',
			[]	
		]
	];

<InnerBlocks  template="<?php echo esc_attr( wp_json_encode( $template ) ) ?>" />

But due to the templateLock="all" applied on the parent block the child block can't insert new blocks. After some research, I've found that maybe templateLock="false" on child block can fix the issue but this InnerBlocks functionality is not available in ACF?

Any solution, suggestions will be much appreciated!

Thanks

Start with the PHP reproduction in the issue and inspect ACF's InnerBlocks support alongside WordPress's parent and child templateLock behavior. Determine whether nested blocks can override the parent's lock, then define the relevant implementation or documentation change and verify it with a focused reproduction.
