The original evidence shows that 朱由⿰木欻, styled 仲梓, was a descendant of 趙王 (朱高燧), who had been enfeoffed in Zhangde Prefecture (彰德府). However, ⿰木欻 is not attested in the local historical gazetteers of Zhangde Prefecture. Instead, all surviving evidence records a different form: ⿲木⿱力力欠.
The character ⿲木⿱力力欠 was also attested in contemporary dictionaries, such as the 成化丁亥重刊改併五音類聚四聲篇: Many characters from this dictionary were used for person names among the imperial descendants of Ming Dynasty.

▲ 《成化丁亥重刊改併五音類聚四聲篇》(明成化刊本)卷7 木部 folio 53b 八畫, quoted from 川篇.
This character can be traced back to a Jin Dynasty dictionary:
▲ 《新修絫音引證群籍玉篇》(金刊本)卷12 木部 folio 31b
Based on the evidence above, I believe that ⿰木欻 is a modern error of ⿲木⿱力力欠. Therefore, I recommend encoding ⿲木⿱力力欠 instead.
Update IDS to ⿲木⿱力力欠, SC=8, FS=5, TS=12.
