Is it possible to make a Block undeletable?

[abikali]

I currently have below Block:

<?php

namespace App\Filament\Fabricator\PageBlocks;

use Filament\Forms\Components\Builder\Block;
use Filament\Forms\Components\TextInput;
use Z3d0X\FilamentFabricator\PageBlocks\PageBlock;

class MyBlock extends PageBlock
{
    public static function getBlockSchema(): Block
    {
        return Block::make('test')
            ->schema([
                TextInput::make('name'),
            ])->icon('heroicon-o-question-mark-circle');
    }

    public static function mutateData(array $data): array
    {
        return $data;
    }
}

Is it possible to make MyBlock non deletable? Something like:

public static function getBlockSchema(): Block
    {
        return Block::make('test')
            ->schema([
                TextInput::make('name'),
            ])->icon('heroicon-o-question-mark-circle')
            ->deletable(false);
    }

Currently above solution throws:
Method 'deletable' not found in \Filament\Forms\Components\Builder\Block

Is it possible to make a single specific block undeletable while others can still be deleted?

Currently, deletable is set on builder component for all or none blocks. Not individual, and that is core filament thing, not package.
