<?php
    public function fromMorph(string $key = '', ?Model $default = null, string $idKeyName = 'id', string $classKeyName = 'class'): ?Model
    {
        $id    = $this->getAttribute($key ? "{$key}.{$idKeyName}" : $idKeyName);

It seems like getAttribute() must be provided by classes using this trait. How about adding it as abstract method to this trait?

        $class = $this->getAttribute($key ? "{$key}.{$classKeyName}" : $classKeyName);
        if (!$id || !$class) {
            return $default;
        }

        $class = Relation::getMorphedModel($class) ?? $class;
        if (!is_a($class, Model::class, true)) {
            return $default;
        }

        $model = $class::find($id);
        if (!$model) {
            return $default;
        }

        return $model;
    }
