Here's how I'd do it. Note the use of when for simplifying optional where conditions (no need to set variables either), and the closure for constraining both the whereHas and the with (if you want to eager load the relationships).

$products = Product::query()
    ->when($request->min_price, function ($query, $min_price) {
        return $query->where('price', '>=', $min_price);
    })
    ->when($request->max_price, function ($query, $max_price) {
        return $query->where('price', '<=', $max_price);
    })
    ->when($request->suboptions, function ($query, $suboptions) {
        $suboptionsConstraint = function ($q) use ($suboptions) {
            return $q->whereIn('id', $suboptions);
        };
        return $query->whereHas('suboptions', $suboptionsContraint)
            ->with(['suboptions' => $suboptionsContraint]);
    })
    ->when($request->brands, function ($query, $brands) {
        $brandsConstraint = function ($q) use ($brands) {
            return $q->whereIn('id', $brands);
        };
        return $query->whereHas('brands', $brandsConstraint)
            ->with(['brands' => $brandsConstraint]);
    });
