How can I compress much smaller than LZMA, that I want repack games?

[Unjk223]

Hello, everybody. I have problem with repack games.

Explanation:
I want to compress smaller than 7z, zip, rar, because I want to make same repack size smaller than others, let's say that I want compress Hedon.ipk3 original file to my repack file (.bin).

Here are about insignificant details: Percent is ratio.
Original before compress: 595 136 KB (100%)
LZMA: 560 360 KB (94%)
Zstandard: 555 498 KB (93%)
Brotli: 555 365 KB (93%)
LZ4: 562 922 KB (95%)
LZ5: 564 075 KB (95%)
Lizard, FastLZ4: 563 373 KB (95%)
Lizard, LlZv1: 560 592 KB (94%)
Lizard, FastLZ4 + Huffman: 562 747 KB (95%)
Lizard, LlZv1 + Huffman: 560 040 KB (94%)
My repack choice (command: precompmt+reflate+xpzlib+xcrilayla+lolz, including oodle7 (Selkie) using Knight Compressor v1.0): 530 846 KB (89%)
Xtool FitGirl Repack: 492 634 KB (all files except DirectX) (82%)

NOTE: Solid on, Thread 1, Word Size 273 of 7Z 21.07 and 7Z 21.03 ZS Standard

I tried everything, but it did not work, however I tried using Knight Compressor v1.0, using command of precompmt+reflate+xpzlib+xcrilayla+lolz (including oodlev7, s), but it did well :/ : 530 846 KB.
However, I want to make my repack smaller as/than FitGirl.
Is there any I can make smaller my repack than LZMA?

Thanks,
