The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antitumor activity of BGB-B2033 alone or in combination with tislelizumab, with or without bevacizumab, in adults with advanced or metastatic hepatocellular carcinoma (HCC), alpha-fetoprotein (AFP)-producing gastric cancer (GC), extragonadal yolk sac tumors, non-dysgerminomas, or glypican-3 (GPC3)-positive squamous non-small cell lung cancer (NSCLC). The study will also determine the recommended Phase 2 dose (RP2D) of BGB-B2033 when given alone or in combination with tislelizumab and bevacizumab. The main questions it aims to answer are: * Is BGB-B2033 safe and tolerable when given alone or in combination with tislelizumab, with or without bevacizumab? * How does the body process BGB-B2033, and what are its effects on the body? * Does BGB-B2033 show preliminary antitumor activity in participants with advanced or metastatic cancer? Researchers will evaluate different doses and treatment combinations to determine the safest and most appropriate dose of BGB-B2033 for further study. Participants will: * Receive BGB-B2033 by intravenous infusion, either alone or in combination with tislelizumab, with or without bevacizumab. * Have regular assessments to monitor safety, side effects, how their body processes and responds to BGB-B2033, and whether their cancer responds to treatment.
