Disable block controls in a block template

[justpie]

Hi All -

I'm building a block which leverages some wordpress/core blocks. When a user drops my block onto the page I want to disable all toolbars for the template items. Ie: When a user tries to modify the core/heading block inside my block, I only want them to beable to control the content.

In the example below, I have the typography set to uppercase

                    <InnerBlocks
                        allowedBlocks={['core/cover']}
                        template={[
                            ['core/cover', coverAttributes, [
                                ['core/heading', {
                                    "style": { 
                                        "typography": {
                                            "textTransform":"uppercase"
                                        }
                                    },
                                    "fontFamily":"united-sans-con"
                                }],
                                ['core/separator'],								
                                ['core/paragraph'],
                            ]]
                        ]}
                    />

I've tried playing around with templateLock, but that only appears to work at the higher level, which disables ALL controls for my block entirely. I was hoping there was a way where I could disable toolbars on a case by case basis, just like in the example below

                    <InnerBlocks
                        allowedBlocks={['core/cover']}
                        template={[
                            ['core/cover', coverAttributes, [
                                ['core/heading', {
                                    "style": { 
                                        "typography": {
                                            "textTransform":"uppercase"
                                        }
                                    },
                                    "settings": {
                                        "typography": {
                                            "fontFamilies": false
                                        }
                                    },
                                    "fontFamily":"united-sans-con"
                                }],
                                ['core/separator'],								
                                ['core/paragraph'],
                            ]]
                        ]}
                    />
