Ignore template from base theme
One way to remove the template from being in the list of suggestions, and ultimately not being used, would be to implement hook_theme_suggestions_alter, and unset it from the $suggestions array. This should effectively remove it, and the next specific template will be used instead.

Alternatively, you can copy the template file in from the base theme, and overwrite it to be a default rendering that is preferable to you (without removing the suggestion) and it will be used instead.
