Prior boundaries for the atmospheric model grids used in this work.

Model	T_eff	log g	[Fe/H]	C/O	R
	(K)		(dex)		(R_Jup)
BT-Settl-CIFIST	1000–2000	2.5–5.5	–	–	0.8–6.0
DRIFT-PHOENIX	1000–2000	3.0–5.5	–0.6–0.3	–	0.8–6.0
Exo-REM	1000–2000	3.5–4.5	–0.5–0.5	0.3–0.75	0.8–6.0

Notes. The boundaries for the effective temperature and the radius were chosen based on previous works on HD 206893 B, while those for the other parameters exploit the maximum allowed range.
