Hi,
I'm confused regarding Asus RT-AC57U V3 router. Is there an OpenWrt version to install on it?
The router is listed on the download page https://openwrt.org/toh/views/toh_fwdownload but there is no link to the firmware.
Does somebody managed to get OpenWrt on RT-AC57U V3 ?

This means that there is no OpenWrt support for this device (yet).
You don't want it either. The v2 and v3 have an ath10k radio which needs more RAM to operate comfortably, more than what Asus endowed them with.
See why the smallbuffer ath10k flavour was introduced:
committed 06:20PM - 22 Dec 19 UTC
According to many bugreports [0][1][2] the default ath10k-ct kernel
module is un… usable on devices with just 64 MiB RAM or with 128 MiB and
dual ath10k cards. The target boards boot but eventually oom-killer
starts to interfere with normal operation, so the current state is
effectively broken.
Since the two patches in question have a performance impact (and
possibly some other unexpected side-effects) a dedicated build variant
is added so that users of the low RAM devices can still benefit from all
the ath10k-ct advantages.
According to testing [3] results, the issue can be experienced even with
"a 256MB device with three radios". Measured performance impact of
implementing small buffers was lowering "the maximum 5 GHz throughput on
an IPQ40xx device without RPS/XPS optimizations from 494/432 Mbit/s for
TCP transfers (download/upload) to 438/343 Mbit/s"
The patches were apparently inspired by QSDK tweaks used by ODMs for the
affected devices.
