Remove settings from Gutenberg core block

Question

From the core/image block in Gutenberg, I am trying to remove both the 'image size' and 'image dimension' settings. Is this possible to do without copying the entire block and removing the parts I wish to omit? The only things that come close to what I want is A) removing an image style:

// Remove 'rounded' default style.
wp.domReady( () => {
  unregisterBlockStyle('core/image', 'rounded');
});

and B) removing a panel from the editor (not a block) with:

const { removeEditorPanel } = wp.data.dispatch('core/edit-post');
removeEditorPanel( 'discussion-panel' );

I could use CSS to hide the settings, but I wish to remove them entirely.

I haven't tried to remove the Image Size settings but you can test this approach I used to remove the Dimension settings for Margin and Padding.

import { select } from '@wordpress/data';
import { addFilter } from '@wordpress/hooks';

/**
 * Component to disable dimension settings based on block context.
 *
 * @param {Object} settings - The block settings object.
 * @param {string} settingsName - The name of the settings being modified.
 * @param {string} clientId - The block id.
 * @param {string} blockName - The block name.
 * @returns {Object} The updated block settings object.
 */
const disableDimensionSettings = (settings, settingsName, clientId, blockName) => {

    // Retrieve current user with capability to update settings
    const { canUser } = select('core');
    const currentUser = canUser('update', 'settings');

    // Retrieve the current post type
    const { getCurrentPostType } = select('core/editor');
    const currentPostType = getCurrentPostType();
    
    // Disable these block settings.
        const disabledBlockSettings = [
            'spacing.padding',
            'spacing.margin',
        ];

    if (
        disabledBlockSettings.includes( settingsName ) &&
        currentPostType === 'page' &&
        !currentUser // Add this condition for Admin only access
    ) {
        return false;
    }

    return settings;
};

addFilter(
    'blockEditor.useSetting.before',
    'my-plugin/disable-dimension-settings',
    disableDimensionSettings
);
