Hello Marco (@michelyweb),
I will consider adding this feature in the future. For now you can unregister these variations by using the following JS code:
wp.domReady( () => {
wp.blocks.unregisterBlockVariation( 'boldblocks/svg-block', 'divider-tilt' );
wp.blocks.unregisterBlockVariation( 'boldblocks/svg-block', 'divider-triangle' );
wp.blocks.unregisterBlockVariation( 'boldblocks/svg-block', 'divider-asymmetrical-triangle' );
wp.blocks.unregisterBlockVariation( 'boldblocks/svg-block', 'divider-waves' );
wp.blocks.unregisterBlockVariation( 'boldblocks/svg-block', 'divider-curve' );
wp.blocks.unregisterBlockVariation( 'boldblocks/svg-block', 'divider-curve-upside-down' );
wp.blocks.unregisterBlockVariation( 'boldblocks/svg-block', 'divider-arrow' );
});
Best, Phi.
